I'm looking at buying another sata hard drive. My question is, it this possible on a n7-S v2.0? I'm allready running a WD raptor on one of the channels. This is a bit of a n00b question, but I'm new to sata. I know that the nf7-s can use sata for raid, but can it be used just to create 2 seperate channels for different sized independent drives?
