Another good article on the best SSDs for the money. I would advise you use this to spec/upgrade your desktops. It appears the author shares the same experience when it comes to Crucial SSDs as I. Had them for I think 2 years now. Still running just as good as when I got them. And I've installed them in over 25 systems. All of which are still running well. But, as with all things, they fail. Never hurts to have a backup. You should always have a good backup.
