Best all-NVMe NAS under $900 (2026)

Updated 2026-11-08

Short answer. Buy the UGREEN NASync DXP480T Plus ($849.99; buy: https://dealectric.com/go/ugreen-nasync-dxp480t-plus), the best all-NVMe NAS under $900 on 2026-11-03 at $899.99 diskless: four M.2 slots, two of them full PCIe x4, a 10-core Intel Core i5-1235U, 10GbE, two Thunderbolt 4 ports and 8 GB DDR5 you can take to 64 GB. Cheaper SSD NAS boxes (TerraMaster F4 SSD $359.99, F8 SSD Plus $799.99, Beelink ME mini $209) run their slots at one or two PCIe 3.0 lanes each, about 1 GB/s a slot.

What the price does not include: the drives. Four 2 TB NVMe SSDs add roughly $1,200 to $1,600 at late-2026 prices (Crucial P3 Plus about $306 to $345 each, Lexar NM790 about $379), four 4 TB drives $2,000 to $3,400, so an 8 TB all-flash build lands near $2,100 to $2,500 before RAID. Its Thunderbolt 4 ports are network links, not a drive mode: reviewers measured 10 to 20 Gb/s to a PC, sometimes no faster than 10GbE. Two years' warranty; the $899.99 is a sale against $999.99 with no end date.

Rows marked with a code and buy link are products Dealectric lists: the price was verified on the brand's own US store on 2026-11-07 and the code is tested daily in that brand's cart; the date shown is its last pass (last check 2026-11-13). The other rows (Asustor, Beelink, LincPlus, QNAP, TerraMaster) are included so the comparison is complete; their figures and prices were read from the makers' own US pages on 2026-11-03 and are not re-checked daily. The buy links are affiliate links: they open the brand's official US store at no cost to the shopper, and the commission pays for the testing; see the disclosure.

Why lanes decide an SSD NAS

An NVMe drive is only as fast as the PCIe lanes feeding it: one PCIe 3.0 lane carries about 985 MB/s, two about 2 GB/s, four PCIe 4.0 lanes about 7 GB/s. The N95, N100, N150 and N305 chips in the cheaper boxes have nine PCIe 3.0 lanes in total, so four to eight slots share them at x1 or x2. The Core i5-1235U in the DXP480T Plus has twenty lanes: two slots get a full x4 and two get x2, plus a separate 2242 slot for the 128 GB system drive. Over a single 10GbE link (about 1.1 GB/s) an x1 slot already saturates the network; the extra lanes matter for RAID rebuilds, local transcoding and the Thunderbolt bridge.

Thunderbolt on a NAS

The DXP480T Plus's two Thunderbolt 4 ports run in host mode: a Mac or PC cannot mount the NAS as an external drive. They form an IP link (a Thunderbolt bridge) that reviewers measured at 10 to 20 Gb/s, with one mini PC gaining nothing over 10GbE, and one Mac owner reporting about 2 GB/s reads after a BIOS update. Asustor's Flashstor Gen2 offers USB4 on the same terms.

Heat

All-flash boxes throttle when drives run hot: a review of the first Flashstor generation found unheatsinked drives at 75–85 °C and throttling when fully populated. UGREEN ships thermal pads for the four drives and has Default, Quiet and Full Speed fan modes; a 100 GB copy measured 40–42 dBA and the CPU reached 69 °C, 71 °C with throttling under a synthetic stress test. Buy drives with heatsinks or fit the pads.
