- I think the times of floppy based tape drives or such with their own
- controller cards and of all kinds of QIC 40/80 times is over. I have
- used such tape drives for years and all the time it was an endless
- series of problems, bugs and disappointment. I really wonder (after
- reading the CMS announcement) how they can call such drives
- high-performance and reliable and so on.
-
- Finally, I sold these drives and moved to a SCSI QIC 1000 drive, one
- of those with 1GB cartridges. It connects easily to any Adaptec (or
- probably other, I haven't tried such, only Adaptec 1542 and 1742) SCSI
- host adapter (no extra card that eats up a slot), has a MTBF of 80000
- hours (compared to 15000 of a CMD DJ-20), provides a speed of about
- 16MB per minute (on large files, of course, otherwise even fast HD's
- aren't seeking fast enough!) and since using it, I did not have ANY
- read error or other reliability problem. 1GB is a convenient size :-)
- and at the time of this writing the 2GB drives are at the same prize
- the 1GB one was when I bought it. The drive is even considerably
- faster than a same-prized DAT drive. With such a drive, you can easily
- implement an efficcient backup strategy without too much work and time
- consumption.
-
- Of course, at a prize of about $1300 it isn't exactly targeted at a
- home user but if you have to rely on it (and it *has* several times
- saved me from big disasters and also made disk upgrades and
- repartitionings quite comfortable), it is money well invested. Also,
- it's a useful archive media.
-
- Such drives are available from Tandberg (TDC-4120 and 4200) and
- Archive (Anaconda series) and possibly other vendors. At least the
- Tandberg drives (which I use) but probably most SCSI-2 drives work
- fine with the GTAK 2.01 software.
