What is ATA / IDE?
The ATA (Advanced Technology Attachment) specification deals with the interface between the motherboard and hard disks that have integrated circuitry. This standard is also referred to as IDE (or Integrated Drive Electronics). Earlier, the hard disk controller had to be separately plugged into an expansion slot, with cables running to the hard disk from the controller. ATA has many versions, which have increasingly improved the features and speeds of the connection. ATA 2 is also called Extended IDE (EIDE) because it introduced support for large drives by using the LBA naming scheme. ATA 6 is the last version of ATA, and is also referred to as ATA/133, which denotes the maximum data rate for the interface— 133 Megabytes per second.
