Currently, Amazon is offering WD 4 TB My Book Duo Desktop RAID 3.1 for $212.50. Selling normally at $260, which is good for an 18 percent discount is the first time we’ve seen it under $250, and it’s a new all-time low. You can take advantage of USB 3.1 speeds with USB-C connectivity. This effectively produces 360MB/s transfers which enable the My Book Duo to work with your Mac from the box. There is also an integrated dual-port USB 3.0 hub, WD NAS-specific red drives and RAID Redundancy optimization. The World Backup Day at the corner is a great time to plan to upgrade your storage game. More than 3,400 clients gave a 4.2/5 star rating.
