I was wondering if there were any tricks that I'm missing here. I have the Samsung XP941 256GB and its only reading at about half of the rate of all the reviews. Write speeds are up near 800 MB/s, but read speeds are only 300-500 MB/s. Seems to be if you can get your rig to recognize it, you were golden. Well I'm installed to it just fine. I couldn't find anything in the BIOS or looking online.

I'm starting to think maybe the disk is bad. Samsung and i don't get along very well, but this seemed to be the best option.
