Some might say that Samsung’s decision to go with TLC NAND for the 840 was a gamble. The technology is new, and they were the first to debut a drive using it. The drive did fall a bit behind in terms of sequential write speeds, but in all honesty, most of the time, you won’t be dealing with sequential writes.
Samsung was able to prove that TLC NAND is a viable solution for future SSDs with the 840. This is great news, considering that TLC is actually cheaper to produce than MLC. Right now, the 840 is roughly the same price as Kingston’s HyperX 3K, however, I still mark it as a good buy.
As for the 840 Pro, there’s not a lot to be said here. This drive is an all-around beast, whether you’re talking about sequential writes, or random reads. What’s more, Samsung is enticing buyers by offering up a free copy of Assassin’s Creed 3 for anyone who purchases an 840 Pro drive. If you want the fastest drive on the market, you want the 840 Pro.
