RE: Any recommendations on a good SCSI backup device?

Of course, if you use Microsoft's RAID, in conjunction with parity
striping in a RAID array, you will achieve RAID level 10. hmmmm.....

I have used NT 4.0's RAID capabilities, and SCSI drives for 2 years
now, without failure, without problem. Had one drive go bad on me and
didn't lose any data. Had I lost any data, I still had my Tape backup.

In my current position we have net servers with large amounts of data
on them, 25 to 30 GB, and we use a RAID array and NT RAID in conjunction
and a DLT drive.

On smaller servers I use DAT drives.

If you have huge data, use DLT, it works very fine. I have a HP
30, not the newest and the best, but very fast and reliable.

RAID5: don't use Microsofts RAID Option comming with NT... use RAID
or don't use RAID, thats my opinion.
