A hard disk drive (HDD), hard disk, hard drive, or fixed disk[b] is an electro-mechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.

  • 15.000 RPM, sustained transfer rates of Transfer Rate Up between 125 Mbytes/sec [1] and 204 Mbytes/sec )(2010)[2] depending on product generation
  • 10.000 RPM
  • 7.200 RPM
