If i'm reading this right then you've just described raid 0+1.

It does look that way, but then I'd make that mistake too. I always mix up 0+1 and 10.

The capacity is the same in either scenario, and with 4 disks, there's no difference really.

Besides, all but the highest end cards wont tell you if it's RAID10 is to the letter or actually 0+1 that it's using. In most cases, RAID10 on low-mid range cards is a mirror of stripes, ime. Particularly if that card only has 4 ports.

Ok cracking thanks all

We use 10 a bit here, depends on the function of the server and whether the demand is on data security or IOPs. RAID5 for your purposes would be more logical on the server. I'd echo the comments about not having one big RAID0 array.. the risks are a little large

Personally I'd be looking at putting *nix, Ubuntu Server or similar, and use Exim as a mail server on the server, rather than windows, but thats just my prejudices showing

I'd be tempted by using Linux again, but the chances of me getting a mail server secure are slim. Last time I delved into Linux was with Suse 9.0 back in 2005

Agreed, raid 5 on the server as I want the redundancy. I was thinking of raid 0 on the main machine purely for speed. Which again I think raid 10 for the main pc is better.
