I have found CD-recordable (or CD-R) to be the most cost effective, secure,
and flexible way to go. Disks are about $7 as piece and store 640 MB. And
no one can screw up and erase the data. Plus you can put researcher's data
on these disks and they can read them on any CD-ROM drive. I'd say at a
research center, this is a BIG selling point, as most computers have CD-ROM
drives (i.e. these researchers could easily use the disks you create), but
you would have to buy Zip or Jazz drives for everyone to make those disks
available.

The down side of CD-R right now is that DVD looms on the horiizon. DVD's
(Digital Video Disk) holds about 2 gigs of data (If you can wait 6 to 12
months, you could just buy one of these..). DVD drives use a smaller
wavelength laser (looks like a 488, actually) to put more data on less
space. Within 2 or three years, the "experts" predict CD-R will be
obsolete. The good thing is they are reverse compatible (If they have two
lasers, as most will) with CD-R disks, so all that data will still be
accessible. Of course, it may bother you to have more lasers on your
storage drive than on your cytometer...:-)

happy shopping.
