So I installed OS as AHCI, flipped the regedit to 0 for iastorv and boots up, changed bios to RAID and setup the array for the two SSD's, and everything works, but performance is weird.

530MB/s Reads, and 830MB/s writes, seems backwards, and low (both samsungs are on sata 6)? Also, I cannot see drive stats in IRST software anymore, it just shows up as unknowns. one array with 2 disks, and 1 solo disk (my boot).

did I do something wrong?

motherboard : ASUS P8Z77-I DELUXE
IRST version : 11.2
2 raid drives : samsung 830 256GB with latest firmware
1 OS drive : Crucial M4 128GB latest firmware

any insight?
