I have two 20 GB drives that I want to put into a RAID 0 setup along with one 60 GB, one for use primarily as a system disc and the other primarily for data storage. My questions are:

How much higher is the failure rate for a HDD in a RAID 0 setup than for a single drive?

What would be the performance difference using the RAID setup as the Photoshop scratch disk and the primary drive vs. using the single 60 GB drive as the scratch disc.

So basically, which drive/setup do I (would you) run as the system drive and which one would you use for data storage? For performance in Photoshop I should obviously(?) use the RAID for data storage and as the scratch disc, but how much risk does that generate vs. using RAID 0 as the system drive and using the single drive for data/scratch or leaving the system disc as the scratch drive?

Anyone with tips regarding this?

failure rates are the same as single drives. nothing has changed, but as you have two of them the changes of failure have essentially doubled as one drive death = array death.

shouldnt be much of a problem provided you backup often.

regarding scratch files, personally i would get as much system ram as possible first, reducing the need for swap/scratch files.

Ok.

The proper question to ask here is:

How many people have had a hard drive failure, that were not a GXP75 or a GXP60?


You will win the lottery before you have a hard disk go out on you, as long as it's not one of those two...
