I do, however, still think that RST is not supporting TRIM under the following conditions/settings:

You are probably the first and only Intel RAID user, who sees such relationship.
Although I don't know the reason for your difficulties to detect any TRIM activity within your RAID0 array, I am nearly sure, that TRIM is passing even through the Intel SATA RAID Controller of your system.
By the way: The topic of this thread was the lost of the IRST icon after the switch from AHCI to RAID. Since this original problem has been solved, it would be fine, if you mark your original question as being answered.
