HDD: performance differences between 7.2k SATA and 15k SAS - Server Fault
It's a case of math. I/O-per-second is determined by the following calculation: Random I/O = 1000/ (average latency + seek time) For a 7.2K RPM drive, a seek-time of 8.5ms and latency of 4.16 gives an IOPS number of 78. For a 15K RPM drive, a seek-time of...
