Disk drive interfaces have evolved from simple interfaces requiring complex controllers to attach to a computer into high level interfaces that present a consistent interface to a computer system regardless of the internal technology of the hard disk drive. The following table lists some common HDD interfaces in chronological order:
Non-standard metricized lengths such as 5 millimetres (0.20 in) are also sometimes encountered. Nearly every brand new computer case comes with a bag of these. They are commonly used for the following purposes, however there are many exceptions: securing a power supply to the case; securing a 3.5-inch hard disk drive to the case

There are adapters, sometimes called a "sled", which can be used to mount a 3.5″ device in a 5.25″ bay. More recently, it is becoming common to use 3.5″ bays for smart card and memory card readers, or for panels with additional USB ports. A 3.5″ drive containing both a card reader and a floppy drive, as well as a USB port, is also ...
