So I just picked up a RIVE, updated to the latest (4206) UEFI and created two RAID arrays:

-2x Samsung 840 Pro (RAID 0)
-3x Western Digital RE (RAID 5)

Now the RAID 0 works just fine, no issues at all. The RAID 5... disappears? I think the issue is really more cosmetic that anything, but I'm not entirely sure. When the system boots it only shows the RAID 0, and states that the 3 WD Black's are not members of a RAID. However, if I press CTRL+I and enter the Intel Matrix Storage Manager, all the information is displayed as expected, showing the RAID 5 as well as that the 3 WD's are members of it.

After installing the RSTe drivers, I'm also seeing both arrays properly from within Windows, and both seem to be fully functional.

To add to my confusion, on a cold boot the arrays appear just fine at startup. It's only on a reboot that the RAID 5 isn't displayed.

For the record, I've checked each drive individually and all appear to be operating flawlessly, not a single read error, reallocated sector or performance problem among them. Now I did have the Raid 5 fail on me once, when I tried to reinstall my system which was on the RAID 0 as UEFI (had been BIOS)... No idea why that happened, but in testing any time I switch between UEFI and BIOS the RAID 5 will fail, even when it hadn't yet been initialized.

Summary:
-On reboot, IMSM does not display the existing RAID 5, however when CTRL+I is pressed all appears correctly, and it appears to behave correctly. The RAID 1 is always displayed correctly. Both arrays are always displayed correctly on a cold boot.
-Booting from UEFI when the RAID was created under BIOS or vice versa causes the RAID 5 to fail, however the RAID 1 does not.
