Nice benches NapalmV5

I have a question though;

I've been using the Areca 1231ML for months now with just 2 Mtron 32GB SSDs on it, and its been fine as an OS disk since.
However I've recentry purchased a pair of velociraptors thinking I can put them onto the Areca, and use them as seconday drives.

Having now installed it and configured the Areca so that the raptors are in RAID0, I cannot find the array in windows, only the origional Mtron SSD array? Can the Areca only be configured to show one array in windows?

I'm thinking of buying the Adaptec 5805 so I can have all 4 drives sharing a hardware RAID controller, with 2 separate RAID0 arrays... is that possible on the 5805? Or it could be done on the Areca just that I suck at configuring it to show?
