What are the two major technologies that are used for hard drives in todays computers?
Shwethakk
A hard disk drive (HDD) is a non-volatile, random access device for digital data. It features rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is magnetically read from and written to the platter by read/write heads that float on a film of air above the platters.
Introduced by IBM in 1956, hard disk drives have fallen in cost and physical size over the years while dramatically increasing in capacity. Hard disk drives have been the dominant device for secondary storage of data in general purpose computers since the early 1960s, They have maintained this position because advances in their areal recording density have kept pace with the requirements for secondary storage. Today's HDDs operate on high-speed serial interfaces; i.e., serial ATA (SATA) or serial attached SCSI (SAS).

∙ 13y agoA hard disk works in pretty much the same way that the old cassette recorders did, there are 2 magnetic heads per disk and usually 2 disks, when you send information to the hard disk, the magnetic heads write the info onto the disk, and likewise retrieve the same info when needed.
