Summary: I must have gotten a bad one. All the other reviewers loved the thing...
Pros: Size, price, speed.
Cons: The device either works great or is temporarily losing track of blocks. Some times it works great and other times I can not boot because this or that file "can not be found" (never the same file two times in a row). Some times it runs for days, other times it fails over and over.
Summary: Bought this to use as a dedicated gaming SSD. Loads games up quick and no stuttering issues. BF4 loads in 45 sec instead of 2 min and CSGO maps load in 5 sec instead of 20. Well worth the buy when it was on sale last year.
Summary: I've been using 256Gb version for 6 months. It's installed on a laptop as an OS drive. So far great performance and no problem. Even though write speed seems less than top ssd products, as an average user, I got nothing but amazing experience. "USE an SSD". Nothing left to say.
