1455.ata atapi standards - 1-7

  1. 1. ATA
  2. 2. ATA - 1 AT Attachment interface for Disk drives 40/44 pin connectors and cabling Master/slave or cable select drive configuration options Signal timing for basic Programmed I/O (PIO) and DMA modes Cylinder, head, sector (CHS) and Logical Block Address (LBA) drive parameters translations supporting drive capacities up to 220–228(267,386,880) sectors, or 136.9GB
  3. 3. ATA - 2 Faster PIO and DMA transfer modes Support for power management Support for removable devices PCMCIA devices support Identifydrive command that reports more information Defined standard CHS/LBA translation methods for drives up to 8.4GB in capacity
  4. 4. ATA - 3 Eliminated single-word (8-bit) DMA transfer protocols Added SMART (Self-Monitoring, Analysis and Reporting Technology) support for prediction of device performance degradation LBA mode support was made mandatory Added security mode, allowing password protection for device access Recommendations for source and receiver bus termination to solve noise issues at higher transfer speeds
  5. 5. ATA/ATAPI - 4 ATA Packet Interface Ultra-DMAtransfer modes up to mode 2, which is 33MBps (called UDMA/33 or UDMA-ATA/33) Integral ATAPI support Defined an optional AT conductor, 40 pin cable for improved noise resistance Compact flash adapter support Introducedenhanced BIOS support for drives over 9.4ZB (Zettabytesor trilliangigabytes) in size
  6. 6. ATA/ATAPI - 5 Ultra-DMAtransfer modes up to mode 4, which is 66MBps (called UDMA/66 or UDMA-ATA/66) 80-conductor cable now mandatory for UDMA/66 operation Added automatic detection for 40 or 80 conductor cables UDMA modes faster than UDMA/33 Enabled only if an 80-conductor cable is detected
  7. 7. ATA/ATAPI - 6 Ultra-DMA transfer modes up to mode 5, which is 100MBps (called UDMA/100 or UDMA- ATA/100) transfers Sector count per command increased from 8- bits to 16-bits, allowing larger files to be transferred more efficiently LBA addressing extended from 228to 248. This feature is often referred to as 48-bit LBA or greater then 137GB support CHS addressing made obsolete
  8. 8. ATA/ATAPI - 7 Addition of another transfer mode called UDMA Mode 6 Allows data transfers up to 133MBps Because of small performance differential between ATA-6 and ATA-7, it is skipped over and instead moved directly to Serial ATA
