Since the invention of the floppy disk drive, various standardized form factors have been used in computing systems. Standardized form factors and interface allow a variety of peripherals and upgrades thereto with no impact to the physical size of a computer system. Drives may slot into a drive bay of the corresponding size.
Compared to flash drives in same form factor, maximum rotating disk drive capacity is much smaller,[citation needed] with 100 TB available in 2018[update],[1] and 32 TB for 2.5-inch.[2]
