I've just come across the Crucial Storage Executive, which is a utility for users of Crucial M500, M550, MX100 & BX100 SSDs. It's a bit like the Samsung Magician utility, in that it allows users to check & update firmware, view S.M.A.R.T info, secure erase an SSD, & perform a PSID revert. It's available in both 64bit & 32bit versions, & best of all, it's free
