Speed is always an enticing feature to have and Hitachi has introduced its 600GB Ultrastar C10K6002.5–inch enterprise hard drive, touted as the fastest professional 10,000RPM hard drive. While it spins at the same speed of some of its rivals, it features 64MB of cache and optimizations to help it transfer data about 15 percent faster in random seeks and 18 percent faster sequentially than the previous best performer. New power management tricks also allow this drive to operate 22 percent more efficiently than its rivals. A 6Gbps SAS link is what offers its speedy data transfers and includes the option for hardware encryption to lock unauthorized access to the data stored within. These drives are already shipping and have been approved for use by computer builders.
