Western Digital Black2 Dual Drive Full Review - 120GB SSD + 1TB HDD in a single 2.5" package
Combined Tests - PCMark Vantage
Figuring many would weigh the Black2 against the hybrid offerings from Seagate, I shamelessly stole the chart from my previous hybrid storage review and adapted it for comparing the Black2 along with some newer SSD results thrown in for good fun:
The SSD portion of the Black2 performs very well when compared to other modern SSD solutions. More impressive is that it clearly dominates the cached performance of the Seagate SSHD. The HDD portion does perform a bit lower, but that is to be expected as it's a lower power solution than Seagate went with.
