Just be aware that the standard 840 is deemed to be inferior to its predecessor, 830. It's the 840 Pro that is all the rage nowadays. I've got Crucials (C300 and M4) in my ToughBooks and love them dearly. Wouldn't say no to 830 or 840 Pro for the next machine. Wouldn't come anywhere near a SanDisk, but that's me. Happy shopping.
