WD's own twist to the hybrid hard drive, the Black2 is a dual drive solution, fusing individual 120GB solid-state and 1TB 5400rpm mechanical drives into a single 2.5-inch package. The Black^2 will be seen as two separate drives on your system, even though they share the same SATA 6Gb/s connector and take a single slot, meaning it can fit in your laptop as a faster disk replacement without issue.
