Microdrive was a brand of tiny [[hard disk]]s—about 25&nbsp;mm (1&nbsp;inch) wide—in a CompactFlash Type II package. The first was developed and released in 1999 by [[IBM]], with a capacity of 170&nbsp;MB. IBM sold its disk drive division, including the Microdrive trademark, to [[Hitachi]] in 2002. Comparable hard disks were also made by other vendors, such as Seagate and Sony. They were available in capacities of up to 8&nbsp;GB but have been superseded by flash memory in cost, capacity, and reliability, and are no longer manufactured.<ref name="Robgalbraith CF info">{{cite web|last=Rob|first=Galbraith|title=Robgalbraith CF info|url=http://www.robgalbraith.com/multi_pagee519.html?cid=6007|publisher=Rob Galbraith|access-date=6 May 2014|archive-date=10 April 2014|archive-url=https://web.archive.org/web/20140410130346/http://www.robgalbraith.com/multi_pagee519.html?cid=6007|url-status=dead}}</ref>

As mechanical devices, CF HDDs drew more current than flash memory's 100 mA maximum. Early versions drew up to 500 mA, but more recent ones drew under 200 mA for reads and under 300 mA for writes. CF HDDs were also susceptible to damage from physical shock or temperature changes. However, CF HDDs had a longer lifespan of write cycles than early flash memories.{{cn|date=February 2024}}

The [[iPod mini]], [[Nokia N91]], [[iriver H10]] (5 or 6&nbsp;GB model), [[LifeDrive]], [[Walkman A Series|Sony NW-A1000/3000]] and [[Rio Carbon]] used a Microdrive to store data.{{cn|date=February 2024}}
