Best All-Flash NVMe NAS

The TerraMaster F8 SSD Plus is our best all-flash NVMe NAS for a shared workspace: eight SSD slots, 16GB RAM and 10GbE leave room for a complete flash array. Choose the ASUSTOR Flashstor 6 Gen2 FS6806X for faster individual SSD interfaces and ECC memory support, or the original FS6706T if you intend to stay with 2.5GbE. These are specification-based picks; the SSD set, network and independent backup matter as much as the enclosure.

Choose flash for active shared projects and demanding file access. For a backup-first purchase, start with our broader best NAS for home shortlist before committing to a full SSD order.

Storage pools, cache and USB enclosures

All three picks specify M.2 2280 NVMe drives. Buy that exact interface and size; M.2 SATA and shorter modules are not interchangeable buying choices for these specified slots.

TerraMaster's storage-pool documentation describes a pool as the disks combined beneath your volumes. Its Hyper Cache documentation describes acceleration for an existing pool. Allocate the SSDs to the main pool for an all-flash build.

• Yes: All-flash storage: SSDs form the pool that holds your volumes and files
• Partly: SSD cache: accelerates an existing storage pool; check the exact NAS's supported role
• No: FS6806X USB4: host-to-host computer connections are not supported

The USB4 limitation comes from ASUSTOR's hardware specifications. For the connection decision, see NAS versus DAS.

Best overall: TerraMaster F8 SSD Plus

Choose the F8 SSD Plus when filling an eight-drive array is the goal. Its official specifications list an i3-N305, 16GB DDR5, one 10GbE copper port and eight PCIe 3.0 x1 SSD slots. The page accepts PCIe 3.0, 4.0 and 5.0 NVMe SSDs, but a newer drive does not change the slot's interface.

TerraMaster lists 64TB raw from eight 8TB SSDs. That is a capacity ceiling claim before RAID, not a guarantee for an arbitrary SSD set. Its cooling design uses fans and heat sinks for the SSDs; fit the supplied thermal parts and preserve airflow rather than adding tall aftermarket assemblies without a clearance check.

Check the software on older stock. The current store page describes TOS 7, while TerraMaster's original datasheet describes TOS 6. The current upgrade instructions specifically tell F8 SSD/Plus owners to update to 6.0.794 before TOS 7, repeating that update manually if it was installed directly from a package. Back up first; follow the instructions for the installed version.

Keep the Plus suffix on the order. The specifications here cover F8 SSD Plus.

Best ASUSTOR upgrade: Flashstor 6 Gen2 FS6806X

The FS6806X is our pick for an ADM-based build with faster SSD interfaces. Its specification page lists Ryzen V3C14, 8GB DDR5, memory expansion to 64GB with ECC support, and one 10GbE port. Check the actual RAM configuration when ordering an ECC upgrade.

Its six SSD links are unequal: one PCIe 4.0 x4, three PCIe 4.0 x2 and two PCIe 4.0 x1. Do not budget for six full-width x4 drives operating at their advertised desktop speeds. Slot interfaces also do not guarantee aggregate array throughput.

This is FS6806X, not FS6706T. The newer interface, memory platform and Ethernet port belong to Gen2; they cannot be carried over to a listing simply called “Flashstor 6.”

See the FS6806X at ASUSTOR

Best for an existing 2.5GbE network: Flashstor 6 FS6706T

The original FS6706T remains a reasonable fit if you will keep a 2.5G network. Its hardware page confirms six PCIe 3.0 x1 NVMe slots, Celeron N5105, 4GB DDR4 and two 2.5GbE ports. For a new 10G workstation build, choose one of the models above.

It is not automatically obsolete: ASUSTOR's status table, checked November 2, 2026, marks FS6706T Generally Available, with software and technical support Supported. That is current status, not a promised support end date.

ASUSTOR's 590MB/s read claim uses SMB Multichannel, RAID 5 and both 2.5GbE ports under optimized laboratory conditions. It does not describe an ordinary connection through a single port. Plan the client configuration before counting on multichannel gains.

See the FS6706T at ASUSTOR

Buy the exact SSD set, then calculate usable capacity

Our concrete drive choices are:

• F8 SSD Plus: WD Red SN700 2TB, WDS200T1R0C. TerraMaster's compatibility table explicitly lists this capacity/model for F8 SSD Plus. The maker's specifications give 2,500TBW endurance for this 2TB version. The warranty ends at five years or the endurance limit, whichever comes first. Do not copy the family's higher endurance headline onto this capacity.
• Either Flashstor: Samsung 990 EVO Plus 2TB, MZ-V9S2T0B/AM. ASUSTOR lists it for FS 67 with ADM 4.3.2 or later, and FS 68 with ADM 5.0.0 or later; both entries identify firmware 1B2QKXG7. Samsung's datasheet specifies 1,200TBW, with a five-year/TBW warranty limit. It is a client SSD with appliance compatibility entries, not a NAS-specific endurance promise.

Those Samsung entries do not mark an extra heatsink as required. Keep cooling under review after installation; a different SSD model or capacity needs a fresh compatibility and heatsink check. These are separate manufacturer validations: the F8 recommendation does not establish Flashstor support for the SN700.

For the worked builds below, we favor RAID 6, which permits two drive failures and sacrifices write performance and capacity for that protection. The documented formula is (drive count − 2) × smallest drive capacity.

These are nominal decimal capacities before system space, filesystem overhead, snapshots and free-space headroom. Size from the files you need to keep, not the raw total.

Audit the Ethernet path before buying faster SSDs

The QNAP QSW-2104-2T-R2 is a useful companion: two 10G RJ45 ports and four 2.5G ports. Connect the NAS and workstation to the 10G pair, then the router to a 2.5G port. This uses both 10G ports; a second 10G workstation calls for a switch with more 10G connections. Check the R2 suffix.

For a desktop without 10GbE, the existing TP-Link TX401 is a concrete option: PCIe 3.0 x4, RJ45, Windows/Linux support and an included 1.5m Cat6A cable. Check the computer's available slot and current drivers. A laptop needs a separately verified adapter for its ports and OS.

TP-Link explicitly warns that actual throughput depends on ports, cable and computer performance. Check the negotiated speed along the entire NAS-to-client path; a gigabit segment remains a bottleneck. Consult our Ethernet cable guide for the installed run. The switch cannot turn the FS6706T's ports into 10GbE.

Add a separate backup destination

A concrete local target is the WD Elements Desktop 20TB, WDBWLG0200HBK-NESN, supplied with a USB-A cable and AC adapter. WD lists computer compatibility rather than certifying these NAS pairings, so confirm that the NAS mounts it and restores files before relying on it.

Use TOS 7 USB Copy or ADM External Storage Backup to copy out of the NAS. Choose a filesystem recognized by the NAS and your intended restore computer. TOS lists NTFS, ext4 and other formats; ADM also lists NTFS and EXT4 for external drives.

Retention changes the sizing. TOS 7 USB Copy's Multi-Version mode stores independent full backups. A 20TB destination cannot hold two full versions of a 12TB dataset. Set retention against actual protected data, allow for growth, and safely disconnect the drive after a completed backup.

ASUSTOR's backup guidance explains that RAID and local snapshots do not create an independent copy. Add an offsite copy: its example is NAS + external hard drive + cloud copy. Restore representative files before retiring the original storage.

1. 1

   Confirm the enclosure

   Match the full model and generation; check software and support status

2. 2

   Match the SSD set

   Use the exact capacity/model entries and their firmware and thermal requirements

3. 3

   Complete the network

   Reserve ports for the NAS, client and router; verify the client adapter and cable

4. 4

   Create the storage

   Install cooling parts and choose the pool, RAID and usable capacity deliberately

5. 5

   Prove recovery

   Run the separate backup, restore files and complete the offsite copy

For a holiday order or gift, assemble that whole list and identify who will administer it before buying the enclosure.

How we choose

This shortlist comes from official hardware pages, datasheets, compatibility entries and software documentation, checked November 2, 2026. No appliances were physically evaluated for this guide. We prioritize complete storage builds, exact generations and usable network paths; manufacturer performance claims remain qualified claims. Capacity examples are calculations, not benchmarks. See How we choose.

Verdict

Buy the F8 SSD Plus for the eight-drive workspace, the FS6806X for an ASUSTOR build with PCIe 4.0 and ECC memory support, or the FS6706T for a home staying on 2.5GbE. Choose the exact SSD set and reserve the backup destination before placing the enclosure order. If that complete kit does not fit the job, reconsider the broader home NAS shortlist.
