Hard Disk Interfaces
Hard Disk Interfaces in this the hard disk drive connects to the PC using an interface. There are various types of interfaces: IDE, SATA, Fiber Channel, SCSI, etc. 1. ATA DATA (IDE/EIDE) IDE (Integrated Drive Electronics) is a standard electronic interface used between a computer motherboard’s data paths or bus and the computer’s disk storage devices, such as hard drives and CD-ROM/DVD drives. The IBM PC Industry Standard Architecture (ISA) 16-bit bus standard is base for the IDE interface, which offers connectivity in computers that use other bus standards. ATA (Advanced Technology Attachment) is the official American National Standards Institute’s (ANSI) name of Integrated Drive Electronics (IDE). 2. Parallel ATA: PATA, based on parallel signaling technology, offers a controller on the disk drive itself and thereby eliminates the need for a separate adaptor card. Parallel ATA standards only allow cable lengths up to 46 centimeters (18 inches). Features of PATA: Relatively...
