The WD Black 2 Dual Drive is a rather unique device that takes mobile storage to the next level. Within one drive, we have both a 120GB SSD for the operating system and a 1TB HDD for additional data. Previously, this could only be achieved through the use of two drives, and in a mobile device such as a notebook that would mean, in most cases, removing the optical drive.
In our testing, the WD Black 2 did quite well on the SSD front. Of course, it's not the highest performing solid state solution, but it does offer quite a performance gain over traditional HDDs and even SSHDs.
The 120GB capacity of the SSD partition seems to be the sweet spot for OS installation, and should offer plenty of additional space for your most used applications. In addition to this, we have a full terabyte of storage space on the HDD portion of the drive, for you to use to your liking.
Personally, I think the WD Black 2 Dual Drive deserves solid consideration if you are in the market for a drive upgrade for your small form factor PCs.
Pricing of the WD Black 2 Dual Drive is set at $299.99 and includes a five-year warranty. This gives the WD Black 2 a 27 cent per GB market price, while HDDs are coming in at 12 to 15 cents per GB. Furthermore, the average price per GB for a typical 120GB SSD sits at 75 to 90 cents per GB.
