If you’re in the market for a ridiculous amount of external storage for your computer, Western Digital has you covered with the latest entry in its My Book Duo storage family. The company announced that it is now offering a 20TB model, which features two 10TB drives operated in RAID.

RAID-1 mode will allow you to mirror the drives for extra redundancy (and peace of mind), leaving you with just 10TB of capacity between the two HDDs within the external enclosure. However, RAID-0 mode enables striping to spread data across both drives, helping to improve overall performance. According to Western Digital, when operating in RAID-0, the My Book Duo 20TB is capable of hitting 360 MB/s sequential reads.

The My Book Duo features a USB 3.1 Type-C port, which allows you to connect directly to modern PCs and laptops without the need for an adapter. Western Digital also includes a cable that that will allow you to connect to “legacy” USB 3.0 and USB 2.0 ports. Also includes are two additional USB Type-A ports on the back of the drive for hooking up accessories like a mouse, keyboard, flash drive, or to simply charge your smartphone.

“Both at home and in the office, people are creating and amassing huge volumes of data, and need high capacity, high speed solutions to easily and confidently move and store that data in a single location,” said Sven Rathjen, Western Digital vice president of product marketing. “There has never been more of a need for a simple-to-use, massive capacity desktop storage solution such as My Book Duo for these content creators to keep pace with their growing storage demands.”

The 20TB My Book Duo joins a family that includes 16GB, 12TB, 10TB, 8TB, 6TB and 4TB SKUs. As the new flagship of the family, the 20TB model, however, will be priced dearly with an MSRP of $799. It is currently available from wd.com and Amazon.
