Thank you very much for your reply! I'm downloading RSTe as we speak, having just uninstalled RST.
I originally had RSTe installed, but opted to install an RST version with a modified installer that forced "compatibility" with X79 systems, because it was the only version of RST/RSTe that allowed TRIM commands (via the Intel SSD Optimizer tool for me) to be sent to SSDs in a SSD RAID-0 volume.
Hopefully the new RSTe supports this, but if not, I guess I'll just wait for RSTe to be updated with this functionality. You don't happen to know of a way to make this work, do you?
Cheers, and thanks again!
Edit:
I installed RSTe, recreated the RAID5 volume on the OROM, booted into windows, and RSTe recognizes it perfectly. Thank you so much for pointing this out!
Unfortunately the Intel SSD Optimizer now gives following message when I attempt TRIM, but this was expected. Also, during the installation of the RSTe package, I had to confirm that I wanted to replace the system's newer driver with the apparently older one RSTe came with. Hopefully Intel updates RSTe with TRIM support for RAIDed SSDs soon! The message follows:
The Intel SSD Optimizer cannot run on a RAID array using an Intel RST driver version earlier than 11.0. Consider upgrading to Intel RST 11.0 or newer to utilize the SSD Optimizer with a RAID0 array.
