I purchased a SM841 SSD from Amazon (Was listed under 840 Pro) that was pulled from laptops. The speeds, according to CrystalDiskMark, are decent (Sequential 500MB W/R were 470ish). However, Samsung Magician does not recognize this SSD as a Samsung SSD and there appear to be no firmware updates. Are there any crucial benefits of Samsung Magician? Are there any generic TRIM programs I can use with this SSD? Thanks for your responses in advance.
