What is the relationship between RPM and gear?

[DiEvelyn]

RPM and gear have a matching relationship. The following is an introduction to RPM: 1. Introduction: Rotational Speed (Rotational-Speed or Rev) refers to the number of revolutions a rotating object makes around a central point per unit time (different from frequency). Common RPM types include rated speed and maximum speed. 2. Structure: Hard drive speed is expressed in revolutions per minute, with the unit denoted as RPM, which stands for Revolutions Per minute. A higher RPM value indicates faster internal transfer rates, shorter access times, and better overall hard drive performance. 3. Function: The spindle motor of a hard drive spins the disk at high speed, generating buoyancy that allows the read/write head to float above the disk. The faster the rotation speed, the shorter the waiting time to bring the target data sector under the head. Therefore, RPM largely determines the speed of a hard drive.
