I grabbed one yesterday. Been watching since late fall and this ties the lowest for a 240-256GB drive without rebates. Yes, they will probably get cheaper through the year, but I'm tired of waiting. Regardless of any perceived performance advantage the Samsung 840 might have, it is still a simple matter of TLC vs MLC. MLC will last longer no doubt. For the same money, I will buy MLC every time.
MLC will also be more likely to maintain its performance over its lifetime, unlike TLC.
