As an MP500 480GB owner, I can say that it's a very hot (~60c idle temp) drive.
And the second downside is that corsair don't want to release a dedicated driver unlike samsung.
In my case this causes "Stornvme, event 11" error message each time my PC starts up.
If I had a chance to get rid of this toaster, I would buy samsung 960Pro or even Evo....
(actually it's not that bad...everything works pretty much fine. There is allways a better choice)
