• Microdrives are miniature hard drive devices engineered to fit into CompactFlash Type II slots. They can be used to transfer data from one computer to another, or as capture points for digital cameras and other devices. "Microdrive" is a proprietary format owned by Hitachi, and all microdrives are either manufactured by Hitachi or produced under license from Hitachi. As with most technology, microdrive specs change frequently, so be sure to consult your device guide for current specifications.
  
  

Storage and Performance

• As of 2010, microdrives are available with storage capacities ranging from 500 MB to 6 GB, making them generally larger than similarly priced Compact Flash cards. Recent microdrives boast a 3600 RPM speed with a read and write speed far above traditional removable storage media. Microdrives are also known for their low power consumption and durability.
  
  

Compatibility

• All microdrives are designed to fit into any CompactFlash Type II device slot. These slots are found on some PC models as well as most consumer and professional-level digital cameras. Microdrive cards work with devices from all manufacturers and are compatible with Windows as well as Apple's OS X operating system, and most image importing and editing software.
  
  

Availability

• Microdrives are available from online retailers specializing in digital cameras and similar devices. They can also be found at big-box electronics retailers, although it is usually best to check online for the latest models and the best prices. You should be able to pick up a new microdrive from wherever you purchased your digital camera.
