Not long ago we took a look at Seagate's Momentus XT
notebook drive. This little speed demon combines both 4GB of solid
state storage along with 500GB of traditional rotational media into the
industry's first "hybrid" SSD-infused hard drive. It offered great
performance, especially after the drive's caching algorithms optimized
data usage models on the drive but its cost was also about 2X
of traditional notebook hard drives of similar capacities. So, as usual, there were trade-offs.
Recently, WD took the time to send us in their fastest 7200 RPM
notebook drive and at 500GB for the largest capacity, I decided to take
the opportunity to do a quick little A/B comparison in performance, over in the HotHardware Blog section. The new
WD Scorpio Black 500GB 2.5-inch notebook hard drive weighs in at half
the price ($76 at Amazon) of the Momentus XT, and as you'll see, does a fairly good job of hanging with it, from a performance standpoint as well.
