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

  1. of the type of disk
  2. from the diameter of the disk
  3. from the diameter of the disk and consequently from the rpm.
  4. diameter
  5. on the surface area of the hard drive
  6. from the diameter radius of the disk itself, because the speed of the disk is inversely proportional to the radius; therefore, the larger the diameter of the radius, the slower the disk will spin, and thus the reading will be slower.
  7. the rpm depends on the latency time.
  8. from the size of the disk
  9. from the diameter of the disk
  10. air
