"So far we have reviewed the Seagate Cheetah 15K.7 and the Savvio 15K.2 and found that the performance of both drives far exceeds anything we have in the consumer market outside of solid state drives. Their 15,000 RPM platters make access times lower and now we are about to test the 10,000 RPM enterprise Savvio from Seagate, the 10K.3.

Seagate’s Savvio Series products use the 2.5-inch wide, 12.5mm tall form factor that is quickly becoming the standard for enterprise servers. This new 2.5-inch form factor allows for more drives to be used in the same amount of space than traditional 3.5-inch drives. In a 1U, 1.75 inch rack mount server you can fit four 3.5-inch drives, but in that same space eight 2.5-inch drives."
