Four bays and Intel transcoding for the least money.

Four bays of storage for backups and direct-play streaming.
Our pick: Cheap 4-bay with 2.5GbE. The Asustor Drivestor 4 Pro AS3304T is a 4-bay NAS powered by the Realtek RTD1296, 4 cores, with 2GB of RAM and 2.5GbE networking. It suits four bays of storage for backups and direct-play streaming. The catch: an older, slow chip with 2GB of RAM: no transcoding to speak of and little room for apps.

Specs are from the Amazon listing or the maker. Prices are for the box without drives unless the listing says otherwise.
An older, slow chip with 2GB of RAM: no transcoding to speak of and little room for apps.
The sweet spot: four drives in RAID 5 or SHR lose only one drive to protection, and you can grow the pool later. Pick this if your library will outgrow one drive.
Cheap 4-bay with 2.5GbE. Four bays and 2.5GbE for a low price. 4.2 stars from 355 ratings. The catch: An older, slow chip with 2GB of RAM: no transcoding to speak of and little room for apps.
It can serve files to Plex players that play them directly, but it has no hardware transcoding, so converting 4K or HEVC on the fly will struggle. For Plex, pick a NAS with an Intel CPU.
No. The price is for the box (diskless) unless the listing you choose says it is a bundle. Add NAS-rated CMR drives such as WD Red Plus or Toshiba N300.
