- 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.
- 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.
- ATA / IDE interface ATA=AT bus Attachment. Parallel ATA used at the PC, Apple Macintosh and some other computers. Now replaced by SATA.
- 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.
- IDE Internal (old) IDE=Integrated Drive Electronics.Developed by Compaq and Western Digital. Newer version of IDE goes under the name ATA=AT bus Attachment.
- 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
- SCSI External D-Sub (PC/Amiga/Apple Macintosh)
- SCSI Internal (2.5 inch)
- SCSI Internal (Differential)
- SCSI Internal (Single-ended) SCSI=Small Computer System Interface. Based on an original design by Shugart Associates. SCSI was ratified in 1986.
- SCSI-2 External Hi D-Sub (Differential)
- SCSI-3 External Hi D-Sub (Differential)
- SCSI-3 External Hi D-Sub (Differential) SCA=Single connector Attachment
- SCSI-3 External Hi D-Sub (Single-ended) SCA=Single connector Attachment
- SCSI-3 Low Voltage Differential/Single Ended (LVD/SE) external connector
- SCSI-II external, Ultra SCSI (Single-ended)
- Serial ATA (SATA) The Serial ATA [SATA] bus is the serial version of the IDE [ATA] spec. Primarily used for hard disk connections.
- Apple PowerBook ATA Used on PowerBooks for the 2.5" drives. The internal hard disk has a 48-pin connector that carries both the ATA signals and the power for the drive.
- Apple PowerBook SCSI these connectors are found on the SCSI Disk adapter cable
