Input:
Having stepped up to thumb drives, external hard drives, and all the "new age" goodies for my computer, I ran across some older ZIP disks with important information on them.  But my drive had log ago disappeared. Found just what I needed, the order was fulfilled in short order and I'm back in business again retrieving info I had believed was long lost.  I even found several boxes of brand new Zip disks I can utilize.  The unit is self sustained, loads it's own driver, is VERY portable as it connects to a USB so that means I can take it with me anywhere.  I highly recommend you purchase one of these units if you have such a need.
