Western Digital now has a 20TB storage box


We here at Bridgenet Wireless Internet service providers has been looking at some company based backup to prevent nasty surprises, this is what we have found. Western Digital has unveiled the 20TB My Book Duo, its highest-capacity storage system yet, and it’s a good example of the pluses and minuses of spinning hard disks compared to SSDs. The system works at either RAID 0, which offers the maximum speed but no backup protection, RAID 1, for full data protection but lower speeds and JBOD (just a bunch of disks). At RAID 0 levels, it offers decent 360 MB/s speeds, enough to do video editing and other disk-intensive chores.

WD says it uses RAID-optimized WD RED drives, which spin at 5,400 RPM, though it doesn’t specify how many. The box includes a USB 3.1 Type-C interface port and two USB 3.0 Type-A ports that can be used to connect flash drives and other accessories to your PC. They can also charge up your smartphone, letting the drive do double-duty as a USB hub (it comes with a USB-C to USB-C and USB-A cable in the box). The My Book Duo also supports 256-bit AES hardware encryption.

The base 4TB model costs R3700, while the top end 20TB configuration will set you back R11000. As a point of comparison, Samsung just unveiled its portable T5 SSD that costs R11000, but you get one-tenth the storage — 2TB. However, you also get a lot more performance, with 540 MB/s from a single drive and the greater reliability of SSDs. In other words, price is the lone advantage left to mechanical disks and the reason why WD is so anxious to keep its relationship with flash storage manufacturer Toshiba.

This is obviously a flagship product but if you are in the market for big storage this is the product to have a look at. Unfortunately not available directly in South Africa yet but we will keep you posted.
