UNAS 2
$307 all-in
Two mirrored drives on a shelf. Runs off a PoE port.
The UNAS 4 adds: four bays, two NVMe slots for cache, RAID 5 or 6, so more space per drive.
GOOD FOR
- No power brick to lose. One PoE++ cable does data and power.
- Small screen on the front shows status.
KNOW BEFORE YOU BUY
- Two bays, RAID 1 only. Half your drive space goes to the mirror.
- 2.5G port, not 10G.
