  2. Hard disk drive interface - Wikipedia

    en.wikipedia.org/wiki/Hard_disk_drive_interface

    Each drive also has an additional power cable, usually direct to the power supply unit. DECs Standard Disk Interconnect (SDI) was an early example of a modern bit serial interface. Fibre Channel (FC) is a successor to parallel SCSI interface on enterprise market.

  3. SCSI connector - Wikipedia

    en.wikipedia.org/wiki/SCSI_connector

    Eventually, there was a desire to combine power and data signals into a single connector. This allows for quick drive replacement, more reliable connections, and is more compact. Most late parallel SCSI disk-drives utilize an 80-pin SCA (Single Connector Attachment) connector.

  4. Ribbon cable - Wikipedia

    en.wikipedia.org/wiki/Ribbon_cable

    A spacing of 0.05 inch (1.27 mm) is the most usual, allowing for a two-row connector with a pin spacing of 0.1 inch (2.54 mm). These types are used for many types of equipment, in particular for interconnections within an enclosure. For personal computers, this size was used in floppy-disk-drive cables and older or custom Parallel ATA cables.

  5. Serial Attached SCSI - Wikipedia

    This form factor is designed for compatibility with SATA but can drive a SAS device. A SAS controller can control SATA drives, but a SATA controller cannot control SAS drives. Lower pins (S1-S7, P1-P11) defined as in SATA. Upper pins S8-S14 provide additional lane of data.

  6. Parallel ATA - Wikipedia

    en.wikipedia.org/wiki/Parallel_ATA

    A drive mode called cable select was described as optional in ATA-1 and has come into fairly widespread use with ATA-5 and later. A drive set to "cable select" automatically configures itself as Device 0 or Device 1, according to its position on the cable. Cable select is controlled by pin 28.

  7. Torx - Wikipedia

    en.wikipedia.org/wiki/Torx

    A security Torx L-key and fastener with holes for a safety pin to hinder disassembly with an ordinary Torx key. A Torx T8 screw head on a hard disk drive.. Torx (pronounced / t ɔːr k s /) is a trademark for a type of screw drive characterized by a 6-point star-shaped pattern, developed in 1967 [1] by Camcar Textron.

  8. Floppy disk drive interface - Wikipedia

    en.wikipedia.org/wiki/Floppy_disk_drive_interface

    A 'universal' cable would have four drive connectors, two for each size of FDD, although cables which have only two drive connectors are common. The cable is normally formed into a ribbon, and a twist located between the pairs of connectors for the drives (see image) is usually applied to the conductors for pins 10 to 16 inclusive.

  9. SCSI - Wikipedia

    en.wikipedia.org/wiki/SCSI

    SASI, which was used in mini- and early microcomputers, defined the interface as using a 50-pin flat ribbon connector which was adopted as the SCSI-1 connector. SASI is a fully compliant subset of SCSI-1 so that many, if not all, of the then-existing SASI controllers were SCSI-1 compatible.
