Most of the SSD manufacturers have utility programs designed to work with their SSD’s. Crucial was missing such a program until recently. http://www.crucial.com/usa/en/support-storage-executive
The program works with M500, M550, MX100, MX200, and BX100 drives, and the name of the program is Crucial Storage Executive. It works in Windows 7, 8 and 8.1.
You can check S.M.A.R.T status, update firmware and check usage with this utility program, among other tasks. When you run the program it will open a window in your default browser.
