I am curious how the 710 or S3700 stacks up against the new M500 from Crucial? I know Intel is kind of the goto for these things but the m500 is power off protected and rated at: Endurance: 72TB total bytes written (TBW), equal to 40GB per day for 5 years . Granted it isn't he fasted pig in the poke but it sure seems like a very reasonable drive for the price: http://www.newegg.com/Product/Product.aspx?Item=20-148-695&ParentOnly=1&IsVirtualParent=1 Sincerely, Joshua D.
