A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device used for storing and retrieving digital information using one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material.

HDDs are accessed over one of a number of bus types, including as of parallel ATA (PATA, also called IDE or EIDE; described before the introduction of SATA as ATA), Serial ATA (SATA), SCSI, Serial Attached SCSI (SAS), and Fibre Channel. Bridge circuitry is sometimes used to connect HDDs to buses with which they cannot communicate natively, such as IEEE 1394, USB and SCSI.

  • 44 pin IDC (2 mm pitch) female
    ATA (44) internal This connector is mostly used for 2.5 IDE HDD of notebooks and so on. Pins 1-40 are the same as the IDE/ATA 40 pin connector, but the spacing between pins is smaller and they are therefore electronically, but not physically compatible.
  • 50 pin IDC male
    ATA (50) internal This connector is mostly used for 2.5 IDE HDD of laptops and some other device. Equal to ATA (44) connector, except 50 pin connector used.
  • 40 pin IDC male
    ATA / IDE interface and cable ATA=AT bus Attachment. Parallel ATA used at the PC, Apple Macintosh and some other computers. Now replaced by SATA.
  • 40 pin IDC female
    ATA 50 to 40 pin (notebook CD-ROM) This adapter will enable you to connect a 50 pin CD-ROM data cable to 40 pin ATA bus.
  • 40 pin IDC female
    ATA to CompactFlash (CF) adapter schematic 
  • ATA/SATA ZIF connector The connector is used in most SSD and 1.8" hard disk storage devices. The device is connected to the controller via flat ribbon cable.
  • 13 pin eSATA USB hybrid (EUHP)
    eSATA USB hybrid (EUHP) external connector 
  • 34 pin IDC male
    Floppy Diskdrive  
  • SCSI All pinouts and some information SCSI stands for Small Computer Systems Interface. It?s a standard for connecting peripherals to your computer via a standard hardware interface, which uses standard SCSI commands
  • 7 pin Serial ATA motheboard internal
    Serial ATA (SATA) The Serial ATA [SATA] bus is the serial version of the IDE [ATA] spec. Primarily used for hard disk connections.
  • ZIF to ATA interface adapter
