WD My Cloud Mirror review: Your private cloud, now with built-in redundancy

July 16, 2014

I liked Western Digital’s My Cloud network-attached storage device when I reviewed it late last year, but relying on a single-drive NAS can be risky. If that drive fails, and you don’t have a backup, you could lose all your data—forever. WD’s My Cloud Mirror solves that problem by putting a second drive in the same enclosure, and configuring the drives as RAID 1. All the same data is written to both drives, so that if one drive fails, you can recover everything from the other. The model reviewed here came with two 2TB drives, yielding 2TB of storage (not 4TB, because the drives are in RAID 1). There’s nothing to stop you from reconfiguring the drives in RAID 0 for blinding speed and 4TB of storage, but that would throw your data-redundancy strategy right out the window. I wouldn’t recommend that unless you’re absolutely fastidious about backing up your NAS—and nobody is fastidious enough to avoid Murphy’s Law.To read this article in full or to leave a comment, please click here
