  2. 2Hardware RAID 0, RAID 1, JBOD and Single modes adapt to speed, capacity or redundancy needs.
  3. 3In RAID 1, data is mirrored: replace a failed drive and the data is rebuilt automatically.
  4. 4Two 3.5″ or 2.5″ SATA drives of up to 22 TB each give up to 44 TB of storage.
  5. 5An intelligent temperature-controlled fan adjusts its speed to keep drives at the right temperature.

Real-life uses

Mirrored backup

RAID 1 keeps two copies of your files so a single drive failure does not stop you.

Photo and video storage

RAID 0 combines two drives for more capacity and faster transfers.

Laptop expansion

Add large external storage to a laptop over a single USB-C cable.

Right for you 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.
