In 2013 we were able to get a hold of Samsung's first go at an OEM M.2 PCIe 2.0 x4 SSD, the XP941. Once word got out about this SSD's speeds many storage enthusiasts thirsted for it. Samsung was not prepared for the consumer market to get so hyped up over it and they stopped distribution to 3rd party resellers as demand was exceeding supply. After a few long months it was finally available again and if you were big on fast storage, this small gum stick SSD was the one for you.

Now, fast forward to 2015. A few weeks ago we took a look at a very fast consumer M.2 SSD, the Kingston HyperX Predator. It offers consumers great speeds as well as endurance, surpassing that of the XP941. Not only that, but it is easily bootable in almost any system. Now, it claims the title of the fastest consumer M.2 PCIe SSD out, however, it isn't the fastest M.2 option to the storage enthusiast.

Today we are going to take a look at Samsung's SM951, an OEM M.2 PCIe 3.0 x4 SSD that offers speeds of up to 2.2GB/s read and 1.5GB/s write! These speeds are almost in line with what the much larger HHHL Intel 750 can do and yet it does this in a M.2 2280 form factor with only a few NAND packages!
