This page is about the the platter (physical spinning) hard drives (disk).

A disk drive is a series of stacked platters with very small heads that read and write the data to the various platters. These platters rotate or spin at very high speeds, currently up to 10,000 rpm (revolution per minute). As disk requests come down from NT Server, the heads move accordingly over the platters to obtain the requested data.



A sector is the minimum unit of transfer in both directions, both reading and writing.
