hard drive!

 Hard disks                                                                             ICT   

A hard drive´s disk will spin between 5400and 7200 RPM. The discs in a hard drive are called platters.

On each disk there are tracks, where the information is saved. Tracks added together make cylinder.

The number of tracks on one disk/platter = number of cylinders in the hard drive.

There is normally one read per disk/platter. The storage of a hard drive is measured in GB´s or TB´s.
