Just to verify that again I just have redone the quick Hex Editor TRIM test on both Operating Systems Win7 and Win8 of my Intel Z77 chipset RAID0 system running the v11.6.2.1002 RST drivers and the v11.6.0.1702 RAID ROM.
Result: TRIM is active within the RAID0 on Windows 7 and Windows 8.
I see - so it's just the Intel SSD Toolbox that can't manually TRIM in Windows 8.

I decided to do the Hex editor test myself to confirm that TRIM is working, using Coup27's method;

Close winhex and delete the file and then empty the recycle bin. Emptying the recycle bin will trigger the trim command. Now leave your PC idle for about 10 minutes. This will give the drives garbage collection time to clean the block where the file was previously stored.

Reopen winhex and take a new snapshot. Search for the offset you noted earlier and next to it should now be a load of zero's. If it is, then you know TRIM is working as that block is now empty (zero = empty).
I did not even have to wait for 10 mins, within 2 mins the file was gone (the offset that the gif file was located at contained all zeroes from that offset onwards) TRIM is definitely working in Windows 8, I am currently using driver 11.2.0.1006 + OROM 11.2.0.1527.
