Advanced Technology Attachment (ATA): This is a disk drive implementation developed by the Small Form Factor (SFF) Committee that integrates the controller on the disk drive itself. There are many versions of ATA, which include ATA: Also known as 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.
