You will not be able to purchase a Samsung SM951 directly from a retailer, as this is SSD is manufactured for OEMs. However, I was recently gifted this from a friend who picked it up in used condition. Great SSD for the value, as this tends to go for $30. Not the best choice if you are going to be storing tons of games, as 256GB is quite limited. But as a boot or file storing drive, this drive has excellent value and mid-tier performance. Pretty much what you'd expect from Samsung.
