I'm currently working out specs for a HyperV server; currently looking at having 2x 10k SAS 146GB drives for the operating systems, and 4x 7200 SATA 250GB drives for the data partitions, but I don't know whether it is worth doing a split like that How did you get on with this?

RAID 5's striping should outperform RAID 1 However, you may be better off investigating a hardware RAID card than trying to build a software RAID from the motherboard sockets. Your gains from RAIDing may be offset by processor overhead.

RAID 1 is mirroring only.
RAID 5’s striping should outperform RAID 1
