QNAP TS-419U+

← Back to the full QNAP NAS list

Status: Legacy / discontinued

A 4-bay 1U rackmount NAS with hot-swappable, lockable trays and a single-core 1.6 GHz Marvell chip. Its 512 MB of DDR3 can't be upgraded, so what it ships with is what you get. It's legacy hardware - fine as a cheap rack file server, not a long-term pick.
