But the bit I don't understand is why have 4 arrays of 3 disks each, giving the equivalent capacity of 8 disks.
To achieve the same capacity you could have 2 arrays of 5 disks, saving 2 disks, or even a single array of 9 disks, saving 3 disks.
If you insisted on using all 12 disks you could have 3 arrays of 4 disks giving the equivalent of 9 disks, 2 arrays of 5 disks giving 10 disks capacity, or even a single array of 12 disks giving 11 disks capacity.
To be fair, I wouldn't go for a single array though.
A word of warning.
At least one of the 12-port raid controllers starts to lose performance after about 8 drives are active. If that's the case then the extra ports are really only suitable for attaching "hot spare" drives - drives which are available for automatic switch-over in the case of failure.

That's the first time you've actually said which controller you've got. The comments I'd seen were about one of the areca cards. I thought I'd give you the warning in case that was what you bought. I've no personal experience with them.
Since you've got 3ware the following is not relevant, but if you think about it, the environment could not be a factor since the individual drives are handled by the controller not the OS. The OS (except for special diagnostic progs) never sees the raw drives so can't possibly affect their performance.

You talking to yourself now?
Either way, the case is finally setup and working properly, even though it's on a slant. I never expected that to be an issue, but that is how things always turn out. Thanks for all the input guys. Till next time.

I understood your meaning.
I had previously looked at the raid controllers and seen the warning, but I hadn't realised from your post that the 9650SE-12ML was one of the raid controllers, I assumed (wrongly) that it was another case.
