A hard disk drive is used to store vast amount of data. The data access time and speed are not critical for this device. The speed of a HDD is specified by the RPM or the rotations per minute of the rotating disc. For an IDE based HDD, the RPM is 5400 or 7200. Faster hard discs with better access time are called SCSI drives which can attain much faster speeds. Since, the HDD works on the principle of rotating disc, its efficiency is restricted by the speed of rotation of mechanical components. Transporting a HDD while in operation may cause a crash and damage the disc.
