TERRAMASTER D2-320 – 2-bay USB RAID enclosure, USB 3.2 Gen2 10 Gbps (diskless)
The D2-320 is a 2-bay hardware RAID enclosure that connects to your computer over USB 3.2 Gen2. Mirror your drives with RAID 1 for backup, or combine them for speed and capacity.
What the D2-320 does for your data
USB 3.2 Gen2 reaches up to 10 Gbps, with up to 521 MB/s from two hard drives in RAID 0.
Hardware RAID 0, RAID 1, JBOD and Single modes adapt to speed, capacity or redundancy needs.
In RAID 1, data is mirrored: replace a failed drive and the data is rebuilt automatically.
Two 3.5″ or 2.5″ SATA drives of up to 22 TB each give up to 44 TB of storage.
An intelligent temperature-controlled fan adjusts its speed to keep drives at the right temperature.
Tool-free trays and the Push-Lock design make drive swaps quick and prevent drives from slipping out.

Backup, sharing, work
Who is it for?
A good choice if…
Home users and freelancers who want a simple, redundant external backup for their computer.
Check before you buy
Supplied diskless: buy SATA drives separately, up to 22 TB each. A USB 3.2 Gen2 port on your computer is needed for 10 Gbps; RAID is not a substitute for a second backup copy.
