Set up RAID 1?

[puckhead193]

So i picked up a G|Raid 3 drive (2tb) Should i set it up as a raid 1 or not? I'm going to be working with HD over FW400 (yay imac see sig.)
So what should I do? I think having a backup is good but will it kill performance?

Thanks

Are we talking software RAID1?

I've never done software RAID1 before, but it's not a complex operation so I wouldn't expect it to use up much of your iMac's resources. And over FW400 you wouldn't see the benefit of RAID0 in terms of speed. So... Your choice.

RAID 1 is good for redundancy, but it's not good for back-up. By that I mean if one drive in RAID 1 goes down you can keeping working off the other drive w/little or no down time (redundancy). If you accidently delete a file, a piece of media randomly goes corrupt, a power surge fries your setup, or, heaven forbid, your dwelling burns to the ground you'll want to have a copy of you files on a separate drive ideally in a separate physical location (back-up).
