Western Digital Raptor 74GB SATA
 

The main barrier that hard drives face is that as opposed to other computer hardware they are still mechanical. Motors, platters, actuator arms and other components, all packed together in a small housing and asked to work in perfect harmony. To increase hard drive performance the answer is simple, increase the RPM (revolutions per minute). Although the answer might be simple its implementation is not, excess heat, limited storage size and dependability have worked against high RPM hard drives. In today’s review we’ll be taking a look at the Western Digital Raptor 74GB SATA, 10,000 RPM, 8MB cache hard drive that dares to go where no hard drive has gone before
