I just installed Panther. A program called ExpressStripe was installed in the Apps folder. Perhaps I have not been paying attention, but I had not heard of it. Apparently, it allows you to manage RAID set ups and you need a root account to use it.

RAID 0 is very bad. I only use RAID 5.

Apple doesn't do any of the writing of the SCSI drivers under OS X. ATTTO Technologies has been taking care of this since the first support for SCSI under OS X. Doesn't surprise me much that ATTO's ExpressStripe is now included in the OS. It's about time too since striping using Apple's utility only allows for RAID arrays that work under OS X but not OS 9. The ExpressStripe allows you to create an array that works in OS X and OS 9 as well.

heres an interesting question. I have two 80GB drives with data on them. If i go and RAID 0 them (i dont back up now, why start?) will i loose all my data or will it be combined logically onto the one volume?

If one drive fails, the whole RAID fails and you lose all collective data.

Whilst I have not tried this on a Mac (all my Macs have been laptops) in the PC world creating a RAID array completely destroys all data on the drives. Basically it's a total re-format.

As noted above RAID 0 basically doubles your risk (but it can get you up to about 80% better disk access speeds).

@G5orbust:
I understand the risks of going to RAID 0 but as i said: I don't backup now so this will not make any difference. Also, I am a FCP person. The advantage of RAID 0 over redundancy AT THIS STAGE is worth any risk.

I also plan on upgrading the mac before disk death would likely occur.
