Western Digital has announced the launch of its My Book Duo. With a capacity of 20 TB, it's the highest capacity external desktop storage unit from the company yet.
The new external disk is aimed mainly at the office users and packs in two 10-TB WD RED HDDs optimised for RAID. The disk is configured for RAID 0 out of the box, while reconfiguring the unit for RAID 1 will mirror data across the two drives.
The new external disk offers read speeds up to 360MB/s via the USB 3.1 Type-C port on RAID 0, while two USB Type-A hub ports and Type-C to Type-C and Type-C to Type-A cables are also included. Security options include password protection and 256-bit AES encryption.
The disk starts at 4 TB, and is the heaviest of the bunch at 2.38 kg (5.25 lb). It is also the most expensive priced at US $800. All capacities, including the 20 TB, are available now.
