U3 was a joint venture between SanDisk and M-Systems, producing a proprietary method of launching Windows software from special USB flash drives. Flash drives adhering to the U3 specification are termed “U3 smart drives”. U3 smart drives come preinstalled with the U3 Launchpad. Applications that comply with U3 specifications are allowed to write files or registry information to the host computer, but they must remove this information when the flash drive is ejected. Customizations and settings are instead stored with the application on the flash drive. Microsoft and SanDisk created a successor called StartKey. SanDisk began phasing out support for U3 Technology in late 2009.
