Tripp,
you will need to buy a SCSI storage unit. Many people on this forum use an external SCSI Zip drive, either the 100 or 250 mb drives. Personally, I use a external SCSI Orb drive. They run about twice as much as a Zip (@ $179) as do the cartridges ($39), but they have a 2 gb storage capability (10-20 times more than a Zip). I have had absolutely no problem with mine. My biggest complaint is how hard it is to get extra cartridges, you pretty much have to get them over the iternet since Best Buy and Circuit City don't carry them. You can also get an external SCSI hard drive or send your unit to Fostex and have them install an internal IEDE hard drive (ande no, it is not very easy or wise to try to install one yourself--you need to the card from Fostex and they don't send instructions!!).
Have fun,
Jim
