Exabytes past the 8200 are fine, but do NOT get an 8200. In fact I run an 8500C at home. The 8200's had problems with some SCSI drivers and do not offer the features the later models do ( ie. reloadable firmware, compression, and fast seek to file mark ). Also, if you buy one used, make sure that it has not had a great deal of hours on it, otherwise a new head assembly will surely be in you near term future. Treated well, the exabytes are an extremely good deal, especially if you are going to store alot of tapes. Data grade 8mm tapes are running a little over $8 these days. Not bad for 5-10Gigabytes of storage. You also find the media very robust. The robustness of the 8mm tapes was demonstrated quite clearly to me soon after I started working at Fermilab. I was shocked to find old fashioned phone with real magnetic bells in them. After some discussion, one of my co-workers clued me into some tests they had run themselves. I needed to see this for myself, so I wrote out a couple of gigs of data on an 8mm tape, and placed it under the phone. After letting the phone ring some twenty or so times, I took the tape back to one of the machines and tried to read it. NO errors. I was amazed. One of these days, I'd like to stick one in an anti-proton beam. It would probably be vaporized, but you never know. :-) ______________________________________________________________________________ Ken Stox ICBMnet: 41:48:8N 88:3:26W email: stox@mcs.net MaBellNet: (630) 969-8109 ______________________________________________________________________________ On Wed, 28 Aug 1996, Richard Foulk wrote: > } I have read just about everything I can get my hands on about backup devices > } for FreeBSD and still can't make a decision.
