Just to clarify the main question regarding the sense and the task of a "Trim Check Tool": There is no need for an application, which verifies at each time of the day or at special situations while working on the computer, if TRIM is currently active within the RAID0 or not (maybe the development of such tool is even impossible). What CyberShadow is trying to develop is a tool, which is able to verify once for ever, if TRIM is active at all within the RAID0 array. The tool should find out, if the TRIM command passes through the related Intel SATA RAID Controller into the RAIDed SSDs. According to my experiences the chances to get positive TRIM test results increase to 100%, when the release of TRIM commands by the OS (Win7/Win8) has been triggered just before doing the TRIM test. This can easily be done by running the "Optimizer" (formerly named Defrag Tool) of Windows 8, but I do not know a similar TRIM command impulse while running Windows 7.
