 REVOLUTIONS PER MINUTE Definition
We define REVOLUTIONS PER MINUTE |
REVOLUTIONS PER MINUTE - A measurement that applies commonly to hard drives, and removable drives like CD-ROMs and DVD-ROMs. It also applies to anything that moves in a circular motion. If you are using a drive with higher RPMs, you usually have better performance. Since the disk is spinning faster the drive can usually read data at a faster rate. For example, 5,400 RPM hard drives are generally slower than 7,200 RPM hard drives. The downside to higher RPM rates is that it is harder to stabilize and read data from a disk that is spinning faster, so the mechanism may be more complex and more expensive. Also, faster spinning drives are usually louder and run hotter. |
