It claims to have power loss protection, and reviews appear to back this up (http://www.anandtech.com/show/8066/crucial-mx100-256gb-512gb-review). I can't see a capacitor on the board... so I'm not sure of the mechanism Micron are using on these guys. The thing that requires attention would be the lifetime - you'll be replacing these far quicker than a more datacenter specific product (the Intel S3700 for example).
