Best 4-bay NAS with built-in 10GbE under $700 (2026)

Updated 2026-11-08

Short answer. Buy the UGREEN NASync DXP4800 Plus ($619.99; buy: https://dealectric.com/go/ugreen-nasync-dxp4800-plus), the cheapest 4-bay NAS with 10GbE built in at its 2026 price, $619.99 diskless on 2026-11-03: 10GbE plus 2.5GbE, an Intel Pentium Gold 8505 with Quick Sync for Plex 4K transcoding, 8 GB DDR5 (to 64 GB), two M.2 slots. The only other 4-bay NAS under $700 with 10GbE built in are UGREEN's DXP4800 GT ($659.99, two 10GbE ports, AMD, no Quick Sync) and QNAP's TS-432X ($659, ARM, SFP+).

The catch: 10GbE pays off only with a 10GbE port or adapter in the computer and a 10GbE switch or direct cable, and UGREEN's single port tops out near 1,250 MB/s, so a two-editor studio wants the GT's second port. The $619.99 is a sale price against $729.99 with no stated end date. The 2.5GbE favourites cost more once a card is added (QNAP TS-464 $639 + QXG-10G1T $139 = $778), and the Synology DS925+ has no 10GbE option at all.

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, Ubiquiti) 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.

Which 10GbE port

RJ45 10GbE (UGREEN, TerraMaster, Asustor) plugs into Cat6a copper and the 10GBase-T ports on prosumer switches and Thunderbolt adapters. SFP+ (QNAP TS-432X, UniFi) needs a transceiver or a direct-attach cable at each end, cheaper per port on a UniFi or MikroTik switch but useless with a copper-only desk. A single 10GbE link moves a 1 GB file in about a second against about 4 seconds on 2.5GbE, provided the drives keep up: four spinning disks in RAID 5 give roughly 400–600 MB/s, so the NVMe slots matter for reads above that.

Plex and transcoding

Hardware transcoding needs an Intel iGPU with Quick Sync (the DXP4800 Plus, TS-464 and F4-424 Pro) or an AMD iGPU with a Plex Pass and driver support (the DXP4800 GT's Vega 8, reported working in reviews but not promised by UGREEN). The ARM units (TS-432X, UNAS Pro 4) cannot transcode 4K; the UNAS Pro 4 runs no apps at all.

Prices and what they are

UGREEN's NAS store showed $619.99 (DXP4800 Plus, against $729.99) and $659.99 (DXP4800 GT) on 2026-11-03 as sale prices with no end date; UGREEN's DXP4800 Pro (Core i3-1315U, 10GbE + 2.5GbE) was $799.99 the same day, over the line. QNAP's store quoted a 2–4 week lead time on the TS-464. TerraMaster's F4-424 Pro price comes from a search snippet of its store; the F4-424 Max was sold out.
