That is no problem for Adaptec 5805
It has fast 1.2GHz dual-core CPU and 512MB DDR2 cache on board - so RAID-5 performance should be identical to RAID-10 (in fact, it should be better, as data is spanned on 4 HDDs, not 2x2 mirrored ones).
As for 2 partitions: I am using that right now, but would prefer single partition for its benefits. Guess I will leave the system as it is right now and wait for proper EFI support from Asus.
