I have similar setup ASROCK Z77 Fatality, I5-3570k, Windows 8 Pro. I have had many issues with Intel RST drivers. I'm using an SSD cache on my C: drive and a RAID 10 on my 4ea 3tb drives.
It's very wonky. I'll have failure of the RST applet to open on startup, I've had failure to shut down properly. Also have had HDD drop from RAID after a forced shutdown (stuck at system is shutting down) and it will need to rebuild and verify. Sometimes
I just cancel the verify because it literally takes days to rebuild with bad disk performance during the process. Just a note, if you firmware update your BIOS you could potentially lose your RAID data, which has happened to me. Basically, unless you have
alot of time on your hands and don't care about your data, go for this software RAID solution, otherwise save yourself a headache and buy a large SSD and and external backup drive (same benefits as RAID or better in every respect), for a home power user anyways,
I doubt many of you on this post are serving databases to medium and large businesses.
