WD Black2 Dual Drive

  • Posted by DCC Scotland on 16 October 2014

On the surface, Western Digital's WD Black2 Dual Drive (WD1001X06XDTL) appears to be simply yet another version of the same hybrid storage idea that's been floating around for a few years now: have a small SSD for fast access backed up by a large HDD, all in the same package. However, the trick to WD's latest product is that instead of using the SSD as an invisible, high-speed cache here the two are kept separate. In one drive you literally get a 120GB SSD and a 1TB hard drive.
What's the advantage of this? Well, first and foremost, most hybrid drives have only 4-8GB of cache whereas the Black2 has a full 120GB. It also means you get to decide what data goes on which drive and you get the performance of an SSD at all times. For instance on a hybrid drive overall transfer speeds are little better than a standard 5,400rpm hard drive because the cache is already full of all your most used programs. With the Black^2, though, you can read and write to the SSD at full pelt. All told, it should theoretically be the ideal speed and capacity upgrade for a laptop or small form factor system.
