This is only ok. I did not find it as good as the WD Blue. sometimes the pc hangs when logging in. My HD app that scans drives sometimes flags this ADATA SD drive as having some bad sectors. It doesn't when I swap it out with the WD blue. I would not buy this one again. It's just "ok". I love how small it is though and install takes seconds. Runs a bit warm. Not a whole lot cooler than a physical drive. I am surprised by that. Either that or it's taking on heat from all the other drives, that is a possibility, but strange nonetheless.
