Best 6-bay NAS with 10GbE and Intel transcoding (2026)
Updated 2026-11-08
Short answer. Buy the UGREEN NASync DXP6800 Pro ($1,099.99; buy: https://dealectric.com/go/ugreen-nasync-dxp6800-pro), the best 6-bay NAS with 10GbE and Intel transcoding for Plex at its 2026 price, $1,099.99 diskless on 2026-11-03: a 10-core Intel Core i5-1235U with Quick Sync, two 10GbE ports measured at a steady 9.5 Gbit/s (Notebookcheck), two Thunderbolt 4 ports, a PCIe x4 slot, 8 GB DDR5 to 64 GB and two M.2 slots. Plex runs in Docker with a Plex Pass for hardware transcoding.
The one rival with the same chip and two 10GbE ports is TerraMaster's F6-424 Max, $999.99 on TerraMaster's store per a search listing (its page could not be read on the day): no Thunderbolt, no PCIe slot, two-year warranty like UGREEN's. Every QNAP 6-bay needs a 10GbE card (QXG-10G1T, no verified US price), and the AMD units (Asustor Lockerstor 6 Gen3, Synology's 2020 DS1621+) have no Quick Sync. Budget the power: Notebookcheck measured 36–42 W idle with four drives, against UGREEN's 25 W hibernating figure, and 34.6 dB(A) at idle.

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, QNAP, Synology, TerraMaster, UGREEN) 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.
What reviewers measured on the DXP6800 Pro
- 10GbE: 9.5 Gbit/s steady in iPerf3 both ways (Notebookcheck, 2026); 8.9 Gbit/s sequential read and 6 Gbit/s write over a mapped share with four WD Red Pro drives in RAID 5 (ITPro, 2024); 2.26 GB/s read and 1.4 GB/s write over CIFS (StorageReview).
- Noise: 34.6 dB(A) idle with hard drives, up to 43 dB(A) under load (Notebookcheck); "remarkably quiet", two 9 cm rear fans (ITPro).
- Power: 22.4 W with no drives, 36.6–41.9 W idle with four IronWolf 4 TB drives (Notebookcheck); about 33 W averaged over a day (Dong Knows Tech). UGREEN's own 24.9 W hibernating figure is lower than any review's idle.
- Plex: not in UGOS's App Center, so it runs in Docker; hardware transcoding needs a Plex Pass. No review published a transcode-stream count for this box; the i5-1235U's Iris Xe decodes HEVC, VP9 and AV1 in hardware (Quick Sync).
Thunderbolt 4 on a NAS
UGREEN's Thunderbolt 4 ports are a point-to-point network link to one computer (a "Thunderbolt" interface with its own IP), not a direct-attached disk, and need a certified cable; UGREEN says Macs run it faster than Windows. No review measured it on this model; treat it as a second fast link for one editing machine, not a 40 Gb/s drive.
Pro or Ultra
The Ultra's Core 5 120U is the same 10-core, 80-EU Iris Xe design with a higher turbo (5.0 vs 4.4 GHz), RAM to 96 GB and a PCIe Gen4 slot; its media engine is the same, so transcoding gains nothing. Six 12 TB drives in RAID 6 give 48 TB usable (about 43.7 TiB) on either.
