I am running these Intel RST(e) drivers v12.0.0.1082 with my Z77 RAID0 and am very satisfied.
By the way: After having flashed the BIOS with the updated Intel EFI RAID "SataDriver" v12.0.0.1783 I have recreated the RAID array and then installed Win8 Pro x64 in EFI mode onto the freshly created RAID0 array. Everything works perfect.
