Updated: 04/26/2017 by Computer Hope

A rotational delay is the amount of time between information requests and how long it takes the hard drive to move to the sector where the requested data is located. In other words, it is a time measurement, in ms (milliseconds), of how long before a rotating drive can transfer data.

Note: Rotational delay is sometimes referred to as rotational latency.
