Sound sampling is the process of converting analogue signals into digital signals. The sound sample is measured by the rate of sampling interval.
Sampling interval is said to be the quality of the sound files or the file size of the sound files are connected to the sampling interval size.

Hard Disk Drive speed is measured depends upon the disk rotational speed, which is estimated in revolutions per minute. The "average rotational latency" is generally based on verified relation in most of the magnetic drives that the "average latency" in milliseconds for such a dive is one half the rotation period.

The two types of hard drives are
(i) Hard disk drives - one or more rotating discs are used in the hard disk drive depends on magnetic storage.
(ii) Solid state drives - It has no movable parts in solid state drives, but it uses "flash memory" as used in the USB flash drives.

The most common standardized form of hard disk drive are 2.5 inch for laptops, and 3.5 inches for desktops.
