Feedback? RAID 0 + Nightly SuperDuper Clone
 
I'm in the process of reconfiguring my hard drives + backup configuration and wanted to see if I could get any feedback on a particular configuration that I *believe* is promising.

First of all, I have a PowerMac G5 and 4 500GB SATA drives. 2 Drives internal and 2 Drives external housed in Icy Dock enclosures and connected via a Firmtek PCIe SATA adapter. My initial test of a RAID 0 on the external disks indicated a roughly 33% increase in speed reading and writing. I knew RAID 0 was fast but this is really fast! With that said, I'm painfully aware that RAID 0 can be a dangerous configuration to run as either drive failing kills the RAID. But honestly I'm not willing to take the performance hit that would come with a RAID 1 and it seems to me that losing a non-raided drive, be it the boot drive or data drive is why we are all using apps like SuperDrive in the first place--reliable backups are the only proof against drive failure. I know several sysadmins that don't even trust RAID 5 for that matter.

The configuration I'm asking for feedback on is pretty simple...
Internal: 2 Drives RAID 0
External: 2 Drives RAID 0
Nightly SuperDuper Clone of internal to external.

Throw in 2 more drives and I'll do monthly offsite rotations too.

What do you think? Is this wise or not? Any comments or other ideas are welcome.

Thanks!

Personally, I'm willing to give up speed -- especially on a backup set -- for more reliability, and wouldn't use RAID0 as a backup destination.

Ok, you said on the backup set...
 
So you wouldn't run RAID 0 as the backup drive but otherwise you would run it as the system drive?

Well, I wouldn't run RAID 0 as a system drive either, but if you're going to take that risk I'd endeavor to be more redundant on the backup.
