I hesitated to write a review but I finally decide ... Product purchased after consulting a number of opinions Using first disk for the OS exclusively. One morning, there was about a month, it is no longer recognized by the system. Test on a different config, ditto. Without conviction, I searched and contacted the manufacturer and after a few email exchanges and procedural referral factory defective product, I just got a brand new product (and new model). In conclusion, OCZ is a serious manufacturer who assumes his problems and manages professional (the world would be easier if everyone did the same)
