Sorry, that was a typo, I have a 950 pro, and Windows 7 doesn't include an m.2 driver, which causes constant problems with booting and starting up after crashes

Sorry, that was a typo, I have a 950 pro, and Windows 7 doesn't include an m.2 driver, which causes constant problems with booting and starting up after crashes. The 850 and 840 are both great drives.
