What does the rotational speed of a hard drive depend on?

  1. from the sum of the seek time, the rotational latency time, and the transfer time.
  2. from the diameter: the larger it is, the lower the speed will be
  3. from the ray
  4. time seek, rotation time, and transfer time
  5. from the diameter of the disc, it is calculated in rpm.
  6. it depends on the size of the disk; a disk with a larger capacity and therefore a larger surface area has a lower rotation speed.
  7. it is inversely proportional to the radius of the disk (therefore to its size)
  8. ray
  9. from the diameter of the disk
  10. from the surface of the disk
  11. from 3 times
  12. from the time it takes for the disk to bring the cluster to the right position.
  13. give 3 sub-tempos
