Basically avoid them at all cost. They're buggy, and Samsung doesn't publicly post their SSD firmware on their website. You need to go through OEM vendors to get it. Anyone who deals with OEM's knows what a PITA it is to get things from them when it involves another company.
Buying drives from CDW or Amazon on your own? Might as well be anal rape in Samsung's book. You're not getting any support nor any updates so that 5 year warranty can get bent.
Stick with their "Pro" consumer SSD's or better yet, buy Intel or Micron. Both Intel and Micron have good firmware support with publicly posted software packages.
That said, hit me up if you just happen to have the latest 883 DCT firmware. I really need it.
