Hope the problem is solved.
I would still recommend to install the new Intel RAID drivers 220.127.116.114
, you'll get better performance and Trim will work.
If you are having problems with your RAID setup when trying to update the Intel RAID driver, unplug SATA and power cables for the RAID HDDs, leave the SSD plugged in and update the Intel RAID/AHCI driver 18.104.22.1684. after reboot and confirmation everything is working, shut down re-connect the RAID array, in the same ports as before, Everything will be as before but with the new RAID driver.
If there are any further issues you can check your BIOS version for an upgrade.
What is your motherboard BIOS version?
Let us know the progress.
