What does RPM stand for in computers

RPM stands for revolutions per minute, and it's used as a measure of how fast any machine is operating at a given time. In cars, rpm measures how many times the engine's crankshaft makes one full rotation every minute, and along with it, how many times each piston goes up and down in its cylinder.Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min) is a measure of the frequency of rotation, specifically the number of rotations around a fixed axis in one minute. It is used as a measure of rotational speed of a mechanical component.RPM stands for "revolutions per minute". A standard hard drive has a spinning disc inside of it - RPM measures how many times that disc spins in a minute. As RPM increases, the speed of your hard drive also increases. So a hard drive with a higher RPM represents a faster hard drive.Although 7200 RPM hard drive are without a doubt faster than 5400 RPM drives, 5400 RPM drives offer an average of 100 MB/s read and writes speeds while 7200 RPM drives deliver an average of 120 MB/s read and writes speeds. ... If you're really looking for performance, then you should consider the 7200 RPM hard drives.
