Well, I may swap it out with a better brand later. I tend to update those backups every month or so. They don't change a lot. Should have stuck with Samsung or whatever, even tho it costs twice as much. I could use the Crusial just to move data from one system to another still. Should be good for that. Dale :-) :-)
