[K12OSN] Two SATA mirrors

[Henry Hartley]

I'm building a small server for use at home and I'd like to set it up with mirrored drives (RAID 1). I also thought I might buy two pairs of drives, one small for the "system" and one large for "content". The motherboard I'm looking at is an ASUS M4A78 PRO which says it supports RAID 1 (among others). 

I haven't set up RAID before and my question, if anyone happens to know, is whether that means that I can set up two independent pairs of RAID 1 mirrors. That is, I want to mirror two 120GB drives and then mirror a second pair of 1TB drives. 

The user manual, which I found on-line, says, "For detailed instructions on how to configure RAID 0, RAID 1, RAID 10, and JBOD, refer to the RAID manual in the support DVD." I can't, however, find the RAID Manual on their web site.

Is what I want to do normally supported? Does anyone have an ASUS motherboard and therefore the support DVD and would be willing to see if anything like this is in the RAID manual (or you could send it to me off-list). Thanks.
