These drives fit into any CompactFlash II slot; however, they may consume more power than flash memory (on the order of 190mA, peak 310mA, at 3.3V) and therefore may not work in some low-power devices (e.g. handheld computers). Nevertheless, they have some benefits over flash memory in terms of the way data is stored and manipulated. Microdrives can store 4 GB or more, but must be formatted for a file system which supports this capacity, such as FAT 32 or NTFS, which may not be supported by older CompactFlash hosts, but it is possible to partition a drive so it will contain a partition less than 4GB.
