An OSD, or Optical Storage Disc, is a small, portable data storage unit that can be used to physically transfer data between computer systems; an OSD's data can also be remotely scanned by omni-tools. OSDs are a key item in upgrade kits. They are also used for storing commercial games for retail, although this appears to have fallen out of favor by 2185.
