In reference to hard disk drives (HDD), what does the acronym RPM stand for?
Rotations Per Minute
Reads per minute
Revolutions per minute
Read/Writes per minute
RPM stands for revolutions per minute, which is a unit of measurement used to quantify how fast something rotates. It's used to indicate how many times an object completes a full rotation in one minute. For example, a hard disk drive may complete 7200 revolutions per minute. When talking about magnetic disk drives, a higher RPM generally means faster read/write speeds and better performance.
