Key Takeaways

• The ASUSTOR Lockerstor 6 Gen2 AS6706T is my best overall pick for buyers seeking a versatile six-bay platform rather than a specialized all-flash or 10GbE-first system.
• The QNAP TS-632X puts 10GbE connectivity at the center of its appeal, which matters most when the network and storage workflow can use that throughput.
• UGREEN’s DXP6800 family splits its appeal across Ultra, Pro, and Plus models, so buyers should compare their exact configuration and intended workload instead of treating the shared six-bay format as interchangeable.
• The Synology DS620slim prioritizes a compact design and 2.5-inch drives, while the Synology FlashStation FS200T takes a very different path with all-flash storage.
• The LincStation N2 combines two SATA bays with four M.2 NVMe slots; its mixed drive layout suits a different storage plan from the conventional six-SATA-bay enclosures in this roundup.

More Details on Our Top Picks

1. ASUSTOR Lockerstor 6 Gen2 AS6706T 6-Bay NAS

   

   Best for Flexible SSD Expansion

   View on Amazon

   The Lockerstor 6 Gen2 gives a six-drive setup unusual room to mix capacity and speed: its six SATA bays sit alongside four M.2 NVMe slots. That makes it a stronger fit for buyers who want SSD caching or separate fast storage than the QNAP TS-664-8G, which has two M.2 slots. Dual 2.5GbE ports offer a step up from basic gigabit networking, while the PCIe slot leaves a path to 10GbE or further storage expansion. Its Celeron processor, expandable 8GB memory, HDMI output, and 4K transcoding support suit a home media library or capable small office. The tradeoff is that it ships without drives, and faster 10GbE requires an add-on card; buyers who need dual 10GbE built in should look at the UGREEN DXP6800 Ultra instead.

   Pros:

   • Four M.2 NVMe slots provide more SSD configuration flexibility than the QNAP TS-664-8G.
   • Dual 2.5GbE ports support faster network access than standard gigabit Ethernet.
   • Memory can be expanded from 8GB to 16GB.
   • HDMI output and 4K media transcoding suit a local media setup.

   Cons:

   • Diskless configuration means the six SATA bays need separately purchased drives.
   • 10GbE requires a separate expansion card.
   • The Celeron platform is less suited to demanding multi-user workloads than the higher-core UGREEN DXP6800 models.

   Best for: Home media organizers and small-office users who want six HDD bays plus several NVMe options for caching or fast storage.

   Not ideal for: Teams that need built-in 10GbE from the start, or buyers who want a populated NAS ready to store files.

   • Processor:Intel Celeron N5105 quad-core, 2 GHz
   • Drive bays:6 SATA
   • M.2 slots:4 M.2 NVMe
   • Memory:8GB DDR4, expandable to 16GB
   • Network:Dual 2.5GbE
   • Expansion:PCIe slot for 10GbE or additional SSD expansion
   • Video output:HDMI
   • Operating system:ASUSTOR Data Master (ADM)
   • Drive inclusion:Diskless
   Our verdict

   “Choose this ASUSTOR if you want a six-bay NAS with especially broad NVMe flexibility and can work within 2.5GbE unless you add a network card.”

2. UGREEN NAS DXP6800 Ultra 6-Bay Network Attached Storage for Teams and Small Businesses

   

   Best for High-Speed Team Storage

   View on Amazon

   The DXP6800 Ultra is the clearest fit here for teams moving large files across a fast wired network: it combines dual 10GbE with a 10-core, 12-thread Intel processor. Compared with the ASUSTOR Lockerstor 6 Gen2, which starts at dual 2.5GbE, the UGREEN can serve more bandwidth-hungry work without a network-card upgrade. Its 8GB DDR5 memory can grow to 96GB, and support for virtual machines and Docker gives administrators more room to run services alongside shared storage. Thunderbolt 4, SD 4.0, USB, and 8K HDMI add useful connection options for creative and office workflows. The cost of that headroom is greater setup complexity: drives are sold separately, and the advertised capacity and performance depend on compatible drives and the rest of the network. For a simpler family media NAS, the QNAP TS-664-8G is a less performance-focused alternative.

   Pros:

   • Dual 10GbE ports target fast, shared access for multi-user workloads.
   • 10-core processor and memory expansion up to 96GB provide room for heavier services.
   • Supports RAID 0, 1, 5, 6, and 10, as well as virtual machines and Docker.
   • Thunderbolt 4, SD 4.0, USB, and 8K HDMI offer a wide range of connections.

   Cons:

   • Drives are not included, so storage must be sourced and configured separately.
   • The 10GbE advantage depends on compatible network equipment and suitable drives.
   • Advanced applications and virtualized workloads require more administration than basic file storage.

   Best for: Small businesses and creative teams that regularly share large files and can make use of dual 10GbE, expandable memory, or hosted applications.

   Not ideal for: Home users with basic backups and media needs, or buyers without 10GbE networking who would leave its main performance advantage unused.

   • Processor:Intel 120U, 10-core, 12-thread, up to 5.0GHz
   • Drive bays:6 SATA bays
   • Maximum stated capacity:Up to 208TB
   • M.2 slots:2 M.2 NVMe
   • Memory:8GB DDR5, expandable to 96GB
   • Network:Dual 10GbE
   • RAID:JBOD, Basic, RAID 0/1/5/6/10
   • Additional connectivity:2 Thunderbolt 4 ports, SD 4.0, USB, 8K HDMI
   • Drive inclusion:Diskless
   Our verdict

   “Pick the DXP6800 Ultra for a small team that can use its built-in dual 10GbE and wants substantial room to expand memory and services.”

3. QNAP TS-673A-8G 6-Bay NAS with Dual 2.5GbE Ports and Two PCIe Gen 3 Slots

   

   Best for PCIe Customization

   View on Amazon

   The QNAP TS-673A-8G suits buyers who want a six-bay system they can tailor as their network and storage needs change. Its two PCIe Gen 3 slots are the main distinction from the QNAP TS-664-8G: they create more room for networking or other expansion, while the two M.2 NVMe slots can support caching or tiered storage. The Ryzen V1500B provides four cores and eight threads, a more workstation-oriented foundation than the Celeron in the TS-664-8G. Dual 2.5GbE supports port trunking, though the listed transfer speed depends on configuration and compatible equipment. QTS and QuTS hero provide a choice of operating systems, but that flexibility may mean more setup decisions than a straightforward home NAS requires. It also lacks the built-in dual 10GbE of the UGREEN DXP6800 Ultra, and its rack-mount design may not suit a living space or desk.

   Pros:

   • Two PCIe Gen 3 slots allow expansion for networking, storage, or other functions.
   • Two M.2 NVMe slots support caching and tiered storage options.
   • Ryzen V1500B supplies four cores and eight threads for varied NAS workloads.
   • Supports both QTS and QuTS hero operating systems.

   Cons:

   • Rack-mount design may be awkward for desktop or living-room placement.
   • Dual 2.5GbE is slower out of the box than the UGREEN DXP6800 Ultra’s dual 10GbE.
   • Expansion and operating-system choices can add configuration work for first-time NAS owners.

   Best for: NAS administrators and small-office users who want PCIe expansion options, NVMe storage, and a choice of QNAP operating systems.

   Not ideal for: Buyers seeking a simple desktop NAS for a home media shelf, or teams that require built-in 10GbE without adding a card.

   • Processor:AMD Ryzen V1500B quad-core, 8 threads, up to 2.2 GHz
   • Drive bays:6
   • Network:2 x 2.5GbE RJ45, compatible with 1GbE and 100MbE
   • PCIe slots:2 x PCIe Gen 3
   • M.2 slots:2 x M.2 PCIe NVMe
   • USB:3 x Type-A USB 3.2 Gen 2, 10 Gbps
   • Operating systems:QTS and QuTS hero
   • Weight:15.6 pounds
   • Warranty:3 years
   Our verdict

   “Choose the TS-673A-8G if PCIe flexibility and QNAP OS options matter more than having 10GbE built in.”

   → See it on Amazon →

4. UGREEN NAS DXP6800 Pro 6-Bay for Teams, Small Businesses File Server

   

   Best Premium Performance

   View on Amazon

   The DXP6800 Pro is the performance-led choice for teams that want a powerful processor and fast networking in one six-bay enclosure. Its 12th Gen Intel Core i5 10-core processor, dual 10GbE ports, and two M.2 NVMe slots put it closer to a compact server than a basic household file box. Compared with the DXP6800 Ultra, it is specified with an i5-1235U and built-in 128GB SSD, while the Ultra lists an Intel 120U and expandable memory up to 96GB; buyers should weigh those distinctions against their workload and configuration needs. Six SATA bays and stated support for up to 208TB give it room for large shared libraries, while Docker and virtual machines broaden its role. This power is excessive for routine backups, and drives are not included. Its advertised 20G aggregation also depends on network setup, compatible equipment, and actual workload conditions.

   Pros:

   • 12th Gen Intel Core i5 processor supports demanding multi-user and application workloads.
   • Dual 10GbE ports can be aggregated for high-bandwidth network use.
   • Six SATA bays plus two M.2 NVMe slots combine bulk storage with SSD options.
   • Built-in 128GB SSD and support for Docker and virtual machines broaden its server role.

   Cons:

   • Diskless storage bays require separate HDD or SSD purchases.
   • Full network throughput depends on compatible 10GbE equipment and configuration.
   • Its performance and business-oriented feature set may be unnecessary for basic home storage.

   Best for: Small businesses and media teams running demanding file-sharing, Docker, or virtual-machine workloads over a 10GbE network.

   Not ideal for: Home users who mainly need backups and streaming, or buyers who want an all-in-one NAS with hard drives already installed.

   • Processor:12th Gen Intel Core i5-1235U, 10-core, 12-thread
   • Drive bays:6 SATA bays
   • M.2 slots:2 M.2 NVMe
   • Maximum stated capacity:Up to 208TB

   • Additional connectivity:2 Thunderbolt 4 ports, USB Type-C, 8K HDMI
   • Drive inclusion:Diskless
   Our verdict

   “Choose the DXP6800 Pro when a small business can use its Core i5, dual 10GbE, and application support rather than paying for unused headroom.”

   → See it on Amazon →

5. QNAP TS-664-8G-US 6 Bay Desktop NAS

   

   Best for Home and Small-Office Basics

   View on Amazon

   The QNAP TS-664-8G-US keeps a six-bay desktop NAS focused on shared files, backups, and media rather than server-class throughput. Its Intel Celeron processor, dual 2.5GbE, and two M.2 slots cover common home and small-office needs, while multiple USB 3.2 Gen 2 ports make external-drive transfers more convenient. Against the ASUSTOR Lockerstor 6 Gen2, it offers fewer NVMe slots—two rather than four—but has a similarly accessible Celeron-class foundation and a desktop form. It is far less network-focused than the UGREEN DXP6800 Ultra, which adds dual 10GbE and a 10-core processor. One specification conflict matters before buying: the listing says the 8GB memory is non-expandable, while the description says support reaches 16GB. Buyers should confirm the exact configuration. This model is a practical fit for everyday storage, not heavy virtualization or high-bandwidth team editing.

   Pros:

   • Six drive bays provide room to build shared storage for home or office use.
   • Dual 2.5GbE ports support faster network access than gigabit-only connections.
   • Two M.2 PCIe Gen 3×2 slots can be used for cache or SSD storage pools.
   • USB 3.2 Gen 2 ports support fast transfers from compatible external drives.

   Cons:

   • The listing conflicts on whether its 8GB memory can be expanded, so configuration details need checking.
   • Two M.2 slots offer less SSD flexibility than the ASUSTOR Lockerstor 6 Gen2’s four.
   • Dual 2.5GbE and a Celeron processor are less suited to demanding team workloads than the UGREEN DXP6800 Ultra.

   Best for: Families and small offices that want a six-bay desktop NAS for centralized files, media, and backups with 2.5GbE networking.

   Not ideal for: Teams with heavy virtual-machine workloads or 10GbE requirements, and buyers who need confirmed memory expansion before purchase.

   • Processor:Intel Celeron N5105 or N5095, quad-core, up to 2.9GHz
   • Drive bays:6
   • Memory:8GB DDR4; listing describes it as non-expandable, while product description states support up to 16GB
   • Network:Dual 2.5GbE
   • M.2 slots:2 x PCIe Gen 3×2 NVMe
   • USB:Multiple USB 3.2 Gen 2 Type-A ports
   • Drive interface:SATA 6 Gb/s
   • Drive inclusion:Diskless
   Our verdict

   “Choose the TS-664-8G-US for everyday six-bay storage if 2.5GbE is sufficient and you verify the memory configuration before buying.”

   → See it on Amazon →

6. UGREEN NAS DXP6800 Plus 6-Bay Desktop NAS, Intel i3 1215u 6-Core CPU

   

   Best for High-Throughput Workloads

   View on Amazon

   The UGREEN NAS DXP6800 Plus is the strongest fit here for buyers who want six conventional drive bays without giving up fast networking or room for SSD caching. Its 10GbE and 2.5GbE ports, six-core Intel i3-1215U, and two NVMe slots make it better suited to large shared files and mixed workloads than the compact Synology DS620slim, which uses 2.5-inch drives and has more modest listed transfer rates. The advertised 208TB maximum depends on compatible drives and RAID setup, and the enclosure ships diskless, so storage needs to be added separately. UGREEN also lists Docker and virtual-machine support, but buyers should be ready to manage a more capable system rather than choosing a minimal backup appliance. For demanding transfers, it offers more headroom than the QNAP TS-632X, though that model adds a PCIe slot.

   Pros:

   • Six SATA bays plus two M.2 NVMe slots provide flexible capacity and cache options.
   • 10GbE and 2.5GbE networking suit large file transfers and multi-device access.
   • Six-core Intel i3-1215U supports Docker and virtual-machine workloads.
   • Includes 8GB DDR5 RAM and a built-in 128GB SSD.

   Cons:

   • Drives are not included, and the stated maximum capacity depends on the chosen drives and RAID configuration.
   • Real transfer speeds depend on the network, storage, and workload, so the 10GbE port alone does not guarantee peak throughput.
   • No Wi-Fi support; network access requires wired Ethernet.

   Best for: Small teams and advanced home-lab users who need six SATA bays, NVMe slots, and 10GbE for large local file transfers.

   Not ideal for: Buyers who want a simple, low-maintenance backup box or Wi-Fi access; this is a wired, diskless system with a feature-rich setup.

   • Drive bays:6 SATA bays
   • M.2 slots:2 M.2 NVMe
   • Processor:Intel Core i3-1215U, 6 cores and 8 threads
   • Memory:8GB DDR5
   • Networking:1 × 10GbE; 1 × 2.5GbE
   • Built-in storage:128GB SSD
   • Maximum listed capacity:208TB
   • Video output:4K HDMI
   • Drive configuration:Diskless
   Our verdict

   “Choose the DXP6800 Plus if you want a six-bay NAS with 10GbE, NVMe expansion, and processing headroom for demanding local workloads.”

7. Synology DS620slim 6-Bay 2.5-Inch NAS Enclosure (Diskless)

   

   Best Compact Six-Bay NAS

   View on Amazon

   The Synology DS620slim earns its place for buyers who need six bays in a notably small enclosure and are comfortable building around 2.5-inch HDDs or SSDs. Its compact 5.94 × 6.89 × 4.76-inch footprint contrasts sharply with the larger, more performance-focused UGREEN DXP6800 Plus, which supports 3.5-inch SATA drives and 10GbE. Synology lists 4K H.265/H.264 transcoding, encrypted read speeds up to 220MB/s, and expandable memory, making this a sensible fit for home media and backup tasks rather than a high-throughput team server. The tradeoff is the restricted drive format: six bays do not translate into the same capacity choices as a conventional 3.5-inch NAS. It also starts with 2GB of memory and comes without drives.

   Pros:

   • Six drive bays fit into a compact desktop enclosure.
   • Supports both 2.5-inch HDDs and SSDs.
   • 4K H.265/H.264 video transcoding supports media-server use.
   • Memory can be expanded from 2GB to 6GB.

   Cons:

   • Limited to 2.5-inch drives, restricting drive choice and capacity compared with 3.5-inch six-bay systems.
   • Listed networking performance is modest beside the 10GbE UGREEN DXP6800 Plus and QNAP TS-632X.
   • Ships diskless with 2GB of DDR3L memory.

   Best for: Home users who want a compact six-bay enclosure for 2.5-inch drives, file sync, backup, and media streaming.

   Not ideal for: Buyers prioritizing high capacity per drive, 10GbE networking, or broad 3.5-inch HDD compatibility.

   • Drive bays:6
   • Drive compatibility:2.5-inch HDDs and SSDs
   • Memory:2GB DDR3L, expandable to 6GB
   • Read speed:Up to 220MB/s
   • Write speed:Up to 190MB/s
   • Video transcoding:4K H.265/H.264
   • Maximum single volume:108TB
   • Dimensions:5.94 × 6.89 × 4.76 inches
   • Drive configuration:Diskless
   Our verdict

   “Pick the DS620slim when a small footprint and six 2.5-inch drive bays matter more than maximum capacity or 10GbE speed.”

   → See it on Amazon →

8. QNAP TS-632X-4G-US 6-Bay 10GbE Desktop NAS

   

   Best for Network Expansion

   View on Amazon

   The QNAP TS-632X stands out for buyers who want fast networking today and a clear path to add hardware later. It combines 10GbE SFP+ with two 2.5GbE ports and a PCIe Gen 3 x4 slot, so it can fit more easily into an existing wired setup or gain additional networking or M.2 SSD expansion. Compared with the UGREEN DXP6800 Plus, it has a quad-core ARM processor rather than a six-core Intel i3, and its 4GB starting memory is less generous. Its advantage is the PCIe slot and stated support for ECC RAM, which may matter more to users planning specific upgrades than to buyers seeking strong performance out of the box. The NAS is diskless, and demanding workloads may call for a memory upgrade.

   Pros:

   • 10GbE SFP+ and dual 2.5GbE ports offer flexible wired connectivity.
   • PCIe Gen 3 x4 slot supports network or M.2 SSD expansion.
   • Memory is expandable to 16GB and ECC RAM is supported.
   • USB One Touch Copy offers a direct route for supported backup tasks.

   Cons:

   • The 4GB non-ECC starting memory may limit demanding workloads until upgraded.
   • Quad-core ARM processing offers less listed CPU headroom than the Intel i3 in the UGREEN DXP6800 Plus.
   • SFP+ networking may require compatible network hardware and cabling.

   Best for: Network-savvy small offices and home-lab builders who want 10GbE SFP+, multiple 2.5GbE ports, and PCIe expansion.

   Not ideal for: Buyers seeking an Intel-based processor, a high memory baseline, or a system ready for demanding applications without upgrades.

   • Drive bays:6
   • Processor:AnnapurnaLabs Alpine AL524 quad-core, 2.0GHz
   • Memory:4GB non-ECC, expandable to 16GB; ECC RAM supported
   • Networking:1 × 10GbE SFP+; 2 × 2.5GbE
   • Expansion:1 × PCIe Gen 3 x4 slot
   • USB:2 × USB 3.2 Gen 1, 5Gbps

9. LincStation N2 6-Bay NAS Server with Intel N100, 16GB LPDDR5, 10GbE, 2 SATA Bays, and 4 M.2 NVMe Slots

   

   Best for NVMe-First Storage

   View on Amazon

   The LincStation N2 is a different kind of six-bay NAS: its six storage positions combine just two SATA bays with four M.2 NVMe slots. That layout favors compact, SSD-heavy builds over the large HDD arrays supported by the UGREEN DXP6800 Plus and QNAP TS-632X. The Intel N100, 16GB LPDDR5, 10GbE port, and included Unraid OS starter license make it appealing for personal cloud use, media streaming, and Docker projects. HDMI 2.0 and USB-C add flexibility for a small home lab. The main compromise is capacity planning: only two bays take SATA drives, and the four NVMe slots require compatible 2280 SSDs. It arrives without drives, so its advertised flexibility still calls for a separate storage budget and some setup comfort.

   Pros:

   • Four M.2 NVMe slots provide substantial SSD layout flexibility.
   • 10GbE networking supports high-speed wired transfers.
   • 16GB LPDDR5 is a generous starting memory configuration.
   • Includes an Unraid OS starter license and HDMI 2.0 output.

   Cons:

   • Only two dedicated SATA bays, unlike the six-SATA-bay UGREEN DXP6800 Plus and QNAP TS-632X.
   • Storage drives are not included, including the required M.2 SSDs for NVMe capacity.
   • Its NVMe-centered layout is less suited to buyers seeking a large HDD archive.

   Best for: Home-lab builders and media enthusiasts who prefer fast NVMe storage, 10GbE, and an Unraid-based system in a compact enclosure.

   Not ideal for: Buyers who want six conventional HDD bays for economical bulk storage or who prefer a turnkey NAS with minimal configuration.

   • Processor:Intel Alder Lake-N N100, 4 cores and 4 threads, up to 3.4GHz
   • Memory:16GB LPDDR5
   • SATA bays:2 for 2.5-inch HDDs
   • M.2 slots:4 for 2280 NVMe SSDs
   • Networking:10GbE
   • Operating system:Unraid OS starter license included

    The Synology FlashStation FS200T suits buyers building a quiet, SSD-based workspace around Synology DSM rather than a bulk HDD archive. Its six 2.5-inch SATA SSD bays and compact desktop form factor make it a more natural fit for low-noise offices and media projects than the QNAP TS-632X, which is aimed at expandable 10GbE networking and conventional six-drive storage. The FS200T offers a 2.5GbE port alongside 1GbE, while its Celeron J4125 and 4GB DDR4 memory are geared toward backup, data management, and container use rather than heavy virtualization. Memory can be expanded to 8GB, but the system remains limited to SATA SSDs. Buyers who want large-capacity HDDs or 10GbE should look instead at the UGREEN DXP6800 Plus.

    Pros:

    • Six 2.5-inch SATA SSD bays support an all-flash setup in a desktop enclosure.
    • Synology DSM provides backup and data-management tools.
    • Includes both 2.5GbE and 1GbE networking.
    • Memory can be expanded from 4GB to 8GB.

    Cons:

    • Limited to 2.5-inch SATA SSDs, unlike six-bay models that support conventional HDD storage.
    • No 10GbE port, leaving it behind the UGREEN DXP6800 Plus and QNAP TS-632X for high-throughput networking.
    • The 4GB default memory and Celeron J4125 are less suited to demanding virtualization workloads.

    Best for: Small offices and home media users who want a quiet Synology DSM system with six SATA SSD bays for backups and shared projects.

    Not ideal for: Teams needing 10GbE, large-capacity 3.5-inch HDD storage, or more memory for demanding virtual machines.

    • Drive bays:6 × 2.5-inch SATA SSD
    • Processor:Intel Celeron J4125 quad-core
    • Memory:4GB DDR4, expandable to 8GB
    • Networking:1 × 2.5GbE; 1 × 1GbE
    • Dimensions:8.9 × 7.99 × 7.28 inches
    • Enclosure:Metal, tabletop
    • Operating system:Synology DSM
    • Warranty:3 years limited hardware warranty
    Our verdict

    “Pick the FS200T for a quiet Synology-based SSD workspace, but choose a 10GbE HDD-capable NAS for bulk storage or heavier workloads.”

11. Asustor Lockerstor 6 Gen2+ AS6706T v2 6 Bay NAS Storage for Content Creator

    

    Best for Creator Workflows

    View on Amazon

    The Lockerstor 6 Gen2+ is the creator-focused pick here: its dual 5GbE ports and four M.2 NVMe slots give media teams more room to build fast shared-storage workflows than the QNAP TS-673A-8G, which has dual 2.5GbE and two M.2 slots. That extra network headroom can help when several workstations move large project files, while NVMe options let you pair bulk HDD capacity with faster storage or caching. Its Intel Celeron N5105 and included 8GB of memory suit file sharing, backups, and media duties, but do not make it a workstation replacement. The tradeoff is that the supplied details do not specify expansion-card slots or a 10GbE card; the listing describes 10GbE upgrade readiness, so buyers should verify the upgrade path before planning around it. It is diskless, too, so storage drives are a separate purchase.

    Pros:

    • Dual 5GbE ports offer more network bandwidth than the QNAP TS-673A-8G’s dual 2.5GbE ports.
    • Four M.2 NVMe slots provide flexibility for caching or high-speed storage.
    • Hybrid HDD and SSD support lets buyers balance bulk capacity with faster media access.
    • Pre-installed 8GB DDR4 memory supports multitasking across backup and media applications.

    Cons:

    • The Intel Celeron N5105 is a modest processor for demanding concurrent workloads.
    • The product is diskless, so buyers must add drives before using its six bays.
    • The supplied details do not spell out a PCIe expansion-card path or exact 10GbE upgrade requirements.

    Best for: Video editors and small creative teams who want six drive bays, faster-than-2.5GbE networking, and multiple NVMe options for shared media storage.

    Not ideal for: Buyers who need a clearly documented PCIe expansion path, a confirmed 10GbE upgrade configuration, or a low-cost NAS for basic backups.

    • Drive bays:6
    • Processor:Intel Celeron N5105 quad-core
    • Memory:8GB DDR4
    • Ethernet:2 x 5GbE
    • M.2 slots:4 x M.2 NVMe
    • Storage support:SATA HDDs and SSDs
    • Video output:HDMI
    • Dimensions:13 x 12 x 13 inches
    Our verdict

    “Choose the Lockerstor 6 Gen2+ if creator workflows benefit from dual 5GbE and four NVMe slots, but verify networking upgrades and budget for drives.”

12. QNAP TS-673A-8G 6-Bay NAS

    

    Best for Expandable Business Storage

    View on Amazon

    The TS-673A-8G earns its place for buyers who want a six-bay NAS they can expand beyond its built-in networking. Its two PCIe Gen 3 slots offer a clear route to add network or other expansion cards, while the Ryzen V1500B provides four cores and eight threads for parallel file-serving and business workloads. Compared with the Asustor Lockerstor 6 Gen2+, the QNAP starts with slower dual 2.5GbE and has two rather than four M.2 slots; its strength is documented expansion flexibility, not the fastest out-of-box creator setup. QTS and QuTS hero give buyers an OS choice, but that flexibility adds decisions around setup and management. The listing also notes entry-level-only NVIDIA graphics support, so it is a poor fit for buyers expecting substantial GPU acceleration.

    Pros:

    • Two PCIe Gen 3 slots provide a defined path for network and other expansion cards.
    • Ryzen V1500B offers four cores and eight threads for concurrent workloads.
    • Two 2.5GbE ports support port trunking.
    • QTS and QuTS hero provide a choice of operating systems, with two M.2 slots for caching or storage tiering.

    Cons:

    • Built-in networking is 2.5GbE rather than the Lockerstor 6 Gen2+’s dual 5GbE.
    • Two M.2 slots provide fewer NVMe options than the Asustor’s four.
    • GPU support is limited to entry-level NVIDIA cards, restricting graphics-intensive workloads.

    Best for: Small-business administrators who want six drive bays, a multi-threaded processor, and PCIe slots for future network or other card upgrades.

    Not ideal for: Creative teams seeking dual 5GbE out of the box, four NVMe slots, or strong GPU-assisted media processing.

    • Drive bays:6
    • Processor:AMD Ryzen V1500B quad-core, 8 threads, up to 2.2 GHz
    • Ethernet:2 x 2.5GbE RJ45
    • PCIe slots:2 x PCIe Gen 3
    • M.2 slots:2 x PCIe NVMe SSD
    • USB ports:3 x USB 3.2 Gen 2 Type-A
    • Operating systems:QTS and QuTS hero
    • Warranty:3 years
    • Enclosure:Metal; tabletop mounting
    Our verdict

    “Pick the TS-673A-8G if PCIe expandability and business-oriented workload flexibility matter more than faster built-in networking or a larger NVMe count.”

How We Picked

I compared these NAS systems by the questions that change a six-bay buying decision: drive compatibility and layout, processor and memory potential, network connectivity, expansion options, and how well each design matches home, creative, or small-business workloads. I also weighed setup and maintenance implications, since a system that needs specialist networking or an all-flash drive budget is a different commitment from a conventional disk-based NAS.

The ranking favors flexibility for the widest range of six-bay buyers, then places specialized systems according to the people they serve best. That puts the ASUSTOR Lockerstor 6 Gen2 AS6706T first as a balanced option, while models such as the QNAP TS-632X, Synology FlashStation FS200T, and LincStation N2 earn distinct roles for network speed, all-flash use, or mixed SATA-and-NVMe layouts. Similar or duplicate listings, including two versions of the ASUSTOR and QNAP names, should be checked by exact model identifier and configuration before purchase; I do not treat a repeated listing as proof of a different hardware revision.

Factors to Consider When Choosing Nas 6 Bay

A six-bay NAS is a chassis choice, not a guarantee of six-drive capacity that suits every workload. I’d work backward from the files, network, and backup plan, then compare the enclosure’s layout and expansion path against those needs.

Decide What the Six Bays Will Hold

Six empty bays can be filled gradually, but the number of drives alone does not determine usable capacity. RAID or another redundancy scheme reserves space for protection, and changing an array later can involve long rebuilds or temporary capacity limits. Decide whether you need fault tolerance, maximum usable storage, or a balance, then check the NAS’s supported storage configurations. Avoid buying drives solely to fill every slot if your current workload needs fewer. A NAS is not a backup by itself, so keep a separate copy of important data even when the array has redundancy.

Match the Network to the Whole Workflow

A 10GbE port only speeds transfers when the NAS, switch or direct connection, client, and cabling can all support it. For several users, aggregate traffic and network design may matter more than a headline port speed. If your clients connect over standard home networking, paying extra for faster NAS networking may leave performance limited elsewhere. Check whether the model offers the ports you need now and whether its expansion options can support future changes. Also factor in the cost and setup effort of upgrading the rest of the network.

Choose SATA, NVMe, or an All-Flash Layout Deliberately

Conventional SATA drives usually make sense for large media libraries, archives, and shared files where capacity matters more than low latency. NVMe can help with workloads involving frequent small files, virtual machines, or caching, but an NVMe slot does not automatically make every task faster. Mixed designs, such as two SATA bays alongside four M.2 slots, need a storage plan that accounts for the different drive types. All-flash systems can deliver a different performance profile, but their drive capacity and replacement costs may change the economics of the whole build. Match the media to the workload rather than filling every available slot with the fastest drive type.

Check Memory, Expansion, and Workload Headroom

File serving and backups place different demands on a NAS than running virtual machines, containers, or multiple services. Before choosing a processor tier, list the applications you expect to run and check whether memory can be expanded to suit them. PCIe slots can add network or storage options, but only if the chassis, supported cards, and operating system work together. A model with more headroom may extend the useful life of a system, while unused expansion features add complexity without helping a simple backup server. Confirm the exact configuration in the listing, since memory and other included components can vary.

Compare Software and Ongoing Maintenance

NAS software shapes everyday tasks such as user permissions, remote access, snapshots, backup scheduling, and drive-health alerts. A feature list is less useful than knowing which services you will actually maintain and how comfortable you are managing them. Check the vendor’s update and support information, plus compatibility for the backup clients and applications you rely on. Plan for drive monitoring, periodic restore checks, and a safe way to apply updates. If several people depend on the system, straightforward administration can be more valuable than spare processing power.

Plan the Full Cost and Backup Path

The enclosure is only one part of a NAS build: drives, network equipment, backup storage, and power use all affect the long-term commitment. Higher-capacity drives can reduce the number of disks needed, while more disks can offer flexibility but add heat and maintenance tasks. Consider whether an off-site copy or cloud backup fits your data volume and connection speed. RAID can keep a system running through some drive failures, but it cannot protect against accidental deletion, theft, or every kind of hardware problem. Make the backup plan before deciding how much of the budget to put into the NAS itself.

Frequently Asked Questions

Is a six-bay NAS a better choice than a four-bay model if I do not need all the capacity yet?

It can be, if you want room to add drives without replacing the enclosure, but unused bays do not automatically make a six-bay system the better fit. Compare the cost of the chassis and the drives you will install now against a smaller NAS that meets current needs. Also check how the model handles adding drives to an existing storage pool; expansion rules differ. If your data growth is uncertain, a larger enclosure can provide flexibility, but keep a separate backup plan either way.

Should I choose 10GbE if my computer only has 2.5GbE?

Not for immediate transfer speed alone: a 2.5GbE client will remain limited by its own connection. A NAS with 10GbE can still make sense if you plan to upgrade clients, connect several fast systems through suitable networking, or use the port for a specific workflow. Check the full path, including the switch, adapters, and cabling, before paying for that capability. If those parts are not planned, prioritize drive layout, software, or backup equipment instead.

Can I mix SATA hard drives and NVMe drives in one NAS?

Some systems support both types, but support does not mean every drive can join the same storage pool or serve the same role. A NAS may use NVMe for cache, a separate pool, or application storage while SATA drives hold bulk files. Confirm the exact model’s supported configurations and the vendor’s compatibility information before buying drives. A mixed layout can be useful when you have a clear fast-storage workload, but it adds setup choices that a simple SATA-only build avoids.

Is an all-flash six-bay NAS worthwhile for a home media library?

Usually, a media library is more capacity-focused than latency-focused, so an all-flash system may not match the workload well. Flash can make sense for frequent small-file access, demanding production work, or services that benefit from fast storage responses. Compare the capacity you need with the drive types supported and the cost of replacing a failed drive. For mostly sequential media playback and archiving, a conventional disk-based NAS may leave more room in the budget for backup storage.

Are the repeated ASUSTOR and QNAP listings different products?

The roundup includes repeated model names: the ASUSTOR Lockerstor 6 Gen2 AS6706T appears alongside an AS6706T v2 listing, and the QNAP TS-673A-8G appears twice. Do not assume the duplicate entries represent distinct hardware or software revisions based on the names alone. Check the manufacturer’s exact model number, included memory, ports, and regional suffix against the seller’s listing. If the specifications match, compare the listing details rather than treating the duplicate as a separate recommendation.

Conclusion

For a single versatile recommendation, I’d choose the ASUSTOR Lockerstor 6 Gen2 AS6706T as best overall. The QNAP TS-632X is my pick for buyers whose workflow can use 10GbE, while the Synology FlashStation FS200T is the best fit for a deliberate all-flash build. For beginners, I’d favor a conventional disk-based system with a clear drive plan and familiar management needs over a specialist design; compare the ASUSTOR and QNAP TS-664 against the software and setup style you prefer. The roundup does not establish a single standout value winner, so I’d compare the exact UGREEN DXP6800 configuration and included features before choosing on value. For compact 2.5-inch-drive storage, consider the Synology DS620slim; for a mixed SATA-and-NVMe layout, look at the LincStation N2. Match the model to your network, drive plan, and backup needs rather than buying six bays for their own sake.
