The floppy disk emulator can provide other systems access to the data on the emulated floppy in a number of ways: Direct access to some dedicated disk partition (e.g.: a 1.44MB partition on a USB key) Floppy file system translation (e.g.: FAT12 floppy ↔ USB key folder) Floppy disk images (e.g.: raw floppy ↔ .img/.iso USB key file)
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.
