| IDE ATA
Abbreviation of either Intelligent Drive Electronics or Integrated Drive
Electronics, depending on who you ask. An IDE interface is an interface for mass storage
devices, in which the controller is integrated into the disk or CD-ROM drive. Although it
really refers to a general technology, most people use the term to refer the ATA
specification, which uses this technology. Short for Advanced Technology Attachment, a
disk drive implementation that integrates the controller on the disk drive itself. There
are several versions of ATA, all developed by the Small Form Factor (SFF) Committee: ATA:
Known also as IDE, supports one or two hard drives, a 16-bit interface and PIO modes 0, 1
and 2. ATA-2: Supports faster PIO modes (3 and 4) and multiword DMA modes (1 and 2). Also
supports logical block addressing (LBA) and block transfers. ATA-2 is marketed as Fast ATA
and Enhanced IDE (EIDE). ATA-3: Minor revision to ATA-2. Ultra-ATA: Also called Ultra-DMA,
ATA-33, and DMA-33, supports multiword DMA mode 3 running at 33 MBps. ATA/66: A version of
ATA proposed by Quantum Corporation, and supported by Intel, that doubles ATA's throughput
to 66 MBps. ATA/100: An updated version of ATA/66 that increases data transfer rates to
100 MBps. |
