Most rotating storage devices rotate at a constant angular rate (constant number of revolutions per second). The maximum rotational delay is simply the reciprocal of the rotational speed (appropriately scaled). In 2001, 7200, 5400 or 4200 revolutions per minute were typical hard disk drive spindle speeds; at 7200 rpm, maximum rotational delay will be 60/7200 s or about 8 ms.</p></blockquote><p></p>
