There's nothing inherently wrong with it. It does what it's supposed to do, it's M.2. The reason I chose this at the time was because I trusted the manufacturing tolerances of Micron, and I thought that other brands were overrated. It saves space, because it can be mounted directly onto the motherboard, in one way or the other. Of course...If I had just waited a little longer I could have bought the new MX500 series SSD, but they don't have any M.2 format drives released yet and there isn't much of significant difference; which is a higher read speed of 560 MB/s and 5 year warranty. The 3 year warranty and read speed of 530 MB/s is just fine!

Not that much of deal compared to some others. But still a decent reference point.
