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, [1] and 32 TB for 2.5-inch. [2] The disk drive size, such as 3.5-inch, is usually refers to the diameter of the disk platters.
