A KeyDrive is basically a bit of flash memory with a USB interface. They're roughly as large as a thumb (so sometimes referred to as "thumb drive") and perfect for carrying one around on your keychain (hence the name "key drive"). Their capacity is commonly 128MB, which makes them a more sensible contemporary means of transporting data than FloppyDisks would be. You can even boot from one, if your BIOS knows how to talk to them. Some RemovableMediaDistribution?s are bootable directly from a KeyDrive, others can use a KeyDrive to make your home directory and other configuration data persistent.
