That said, understanding the capabilities and shortcomings of these devices is important to maintaining a well-run SAN environment—especially where high-performance I/O operations are required. The rotational speed of a drive, its average seek time performance, the relative location of the tracks being used, the number of applications sharing space on the drive, and the amount of buffer memory are all contributing factors that need to be considered for ...
