Yeah I want to get the most performance out of my HDs, but only if I can afford a hardware RAID card. > 2) There is no way around backing everything up and restoring when > reconfiguring a raid.

And what if you want to add two new HDs to channel #2 of the card, what if you disconnect the striped HDs from channel 1# then set the switch to normal, format the two new drives, then set the switch back and format them again for striping, and then connect the other HD's back to channel #1, would that work, or will the drives loose the data then? > Then again, we use higer levels of RAID (RAID 5) Didn't know there were even higher RAID levels. > The only time to choose > raid 0 imo is when you absolutely *have* to have the maximum > performance, and you do your backups religiously! Yeah that would be a good idea. Does anyone know if it's possible to stripe the Maxtor UATA 133 with a stock Quantum 6 gig from a B&W, or do both HDs have to be the same UATA speed? -- Marc van Gemert | MacSonar Support Team | Webmaster MacSonar http://www.MacSonar.net | mailto:[EMAIL PROTECTED] -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
