The Addonics Internal UDD (Ultra DigiDrive) offers the same versatility as the Pocket UDD. It can read/write to PCMCIA hard drives and ATA Flash memory with USB 2.0/1.1 or Serial ATA connections to any Desktop or Notebook computer. By using an optional CF DigiAdapter or the Addonics 4-in-1 DigiAdapter, the Internal UDD can also be used like a regular floppy drive to read/write to other popular Flash media - CF-I, CF-II, Smart Media, Memory stick, Secure Digital Card, Multimedia Card or Micro Drive. Even the latest XD Card from Fuji and Olympus can now be used on your Desktop PC via the XD PCMCIA adapter. The UDD supports up to 480 Mbits/sec (60 MB/sec) data transfer with USB 2.0, 10 times the speed of USB 1.1, and up to 1,500 Mbits/sec (150 MB/sec) data transfer with Serial ATA.
