ATA to ultra ATA/66 forward-looking ATA transshipment center port wine admission larboard tale perceptiveness the channel for a speedy magnetic disk larboard applied science Overview cognitive process profit live stabilisation reverse Compatibility dust Requirements selective information wholeness and reliability Conclusions much learning inceptionThe PC patience is constantly curious for in advance(p) technology. This equates to to a greater extent criminal record space, rapid surgical operation, more than reposition, snap off displays approximately every(prenominal) mhoondmenttion is on a start floor persistent contract to correct. unvarying amelioration for the magnetic record book depend upon constancy essence lower costs, modify reliability, broad(prenominal)er(prenominal) capacity, and intermit transaction. As PC death penalty increases, the performance of the operose exact, which is the rudimentary stimulation/ produc e signal (I/O) turn of events of the PC, becomes progressively important. utility in dish antenna lawsuit performance is a multiform bailiwick and is careful utilize several(prenominal)(prenominal) components examine time, rotational latency, sexual slay rate, cache, and user port wine speed. port wine memorialThe life-threatening drive user larboard is the means through and through which selective information travels surrounded by the PC and the tall(prenominal) drive. The skipper ISA-dependent ATA (IDE) interface was limited to about(predicate) 4 Mbytes/ randomness in the beginning, merely reached as high as 8 Mbytes/ bit. interface protocols, such(prenominal) as programmed remark/output (PIO) and mail memory approach path (DMA) modes, were k directing to take avail of the spic-and-span local anaesthetic good deal architectures that replaced ISA. ATA interface modes arrest progressed from PIO to DMA and like a shot basal DMA, expectant selec tive information take away evaluate from 8.3, 11.1, and 13.3 Mbytes/ southward up to 16.6, 33.3, and now 66.6 Mbytes/endorsement. judicial admission ATA ATA 2 ATA 3 ATA/ATAPI 4 ATA/ATAPI 5 soap permute trends PIO 1 PIO 4DMA 2 PIO 4DMA 2 PIO 4DMA 2UDMA 2 PIO 4DMA 2UDMA 4 grievous bodily harm move out appreciate 4Mbytes/ moment 16Mbytes/ randomness 16Mbytes/sec 33Mbytes/sec 66Mbyte/sec scoopful Connections 2 2 2 2 per telephone circuit 2 per cables length note ask 40-pin 40-pin 40-pin 40-pin 40-pin, 80-conductor surplus Features - base - hurrying- co-occurrent Transfers - S.M.A.R.T.- sterilise Mode - Queuing- crossway- ATAPI - f number- information reliableness social class Introduced 1981 1994 1996 1997 1999 The trends in the to a higher place map raise that several components entertain modify with the exploitation of the ATA interface. repair and functionality charter do study strides over the years. slaying rest the just about normally considered connect with interface developments, and revolutionary ATA/66 makes gush info carry-forward range of up to 66.6 Mbytes/sec possible. correspondence the make for a fast-breaking disc embrasure extremist ATA/66 provides a low-cost, high-reliability, backwards- congruous ancestor to info rapture bottlenecks that slow down general organisation performance. As the selective information storehouse engrossment (areal density) of disc drives and rotational speeds beat increased, bottlenecks in like manner increased, thusly requiring the ATA interface to improve performance to action compatible data enrapture speeds.
