How much faster is solid state disk than a hard drive?
A good hard disk drive provides access times in the 4-5 millisecond range. A DSI solid state disk has an access time of 15 microseconds. A DSI solid state disk is 250 times faster than a hard disk drive. A good hard disk drive provides 250-300 random I/O’s per second. The DSI solid state disk provides over 400,000 random I/O’s per second. It would take 1,333 hard disk drives to match this total I/O performance.
