You are absolutely wrong!

When the "Customize" button of the Intel SSD Toolbox is greyed out or the optimization doesn't have any effect, it only means, that the manually invoked TRIM feature of Intel's SSD Toolbox doesn't work with the related SSDs or Operating System, but it doesn't mean, that the permanently active "TRIM in RAID0" feature of the actual Intel RST drivers doesn't work.

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.
