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

  1. the rpm depends on the latency time.
  2. from the size of the disk
  3. from the diameter of the disk
  4. air
  5. from the diameter and from wear
  6. from the number of discs and from the diameter
  7. the diameter of the disk
  8. A
  9. from the sum of the seek time, the rotational latency time, and the transfer time.
  10. from the diameter: the larger it is, the lower the speed will be
  11. from the ray
  12. time seek, rotation time, and transfer time
  13. from the diameter of the disc, it is calculated in rpm.
  14. 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.
  15. it is inversely proportional to the radius of the disk (therefore to its size)
  16. ray
  17. from the diameter of the disk
  18. from the surface of the disk
  19. from 3 times
  20. from the time it takes for the disk to bring the cluster to the right position.
  21. give 3 sub-tempos
