 Advanced Technology Attachment

Advanced Technology Attachment

  • ATA stands for Advanced Technology Attachment. ATA is that the older name of PATA.
  • ATA is renamed Parallel ATA (PATA) when newer Serial ATA (SATA) was introduced. ATA may be a standard physical interface that connects the storage devices like hard-drive, CD-ROM, and other drives to the motherboard.
  • ATA standards only allow cable up to 18 inches due to which it works internally. It's designed to attach portable storage devices without using an external controller.
  • ATA is that the commonest and low cost interface that gives a reliable speed. It's basically made from thin wires and cable bus.
  • It's also referred to as Integrated Device Electronics (IDE). The ATA standards are backward compatible.
  • It means each newer version of ATA or new ATA drives are often used with older ATA interfaces.


  • The first version of ATA was developed by the company named Western Digital in 1986. Originally, it had been referred to as ATA but after the introduction of SATA (Serial ATA) in 2003, it became PATA. Both PATA and SATA are IDE (Integrated Drive Electronics) devices.


  • ATA uses 40 pins connectors on either side of the cable and 40 or 80 wire designs. One end is connected to the motherboard and other is connected to the hard drive.
  • PATA uses one Bus but multiple wires. ATA are often connected to two devices at a time, one is named slave and other is called master.


  • The main reason for SATA is that the increased data transfer speed and that’s why it's preferred over PATA in use.
  • The length of the cable linking connection from the hard drive to the pc motherboard is another advantage of SATA over PATA.
  • The SATA connection links on a computer motherboard are four to six, permitting for more than one SATA hard drives to be curved up like a hook.


  • SATA hard drives at some unspecified time need an exceptional driver for the pc to identify and utilize the drive.
  • The cable of SATA permits just one SATA hard drive to be made link connection at a time.
