IS-400 Pro product photo

Status: Legacy / discontinued

A rugged, fanless 4-bay industrial NAS built for harsh environments, taking 2.5-inch drives or SSDs only. It runs an Intel Celeron dual-core with 2 GB of RAM and accepts 9-36V DC terminal power as well as an adapter. Memory can't be upgraded and it dates to 2014, so it's a legacy pick for specialty installs.
