Samsung evo 840 ssd
At the price that you are paying, this SSD is does a pretty cool job. There are only 2 Brands that you can rely on, Samsung and Crucial. Though I didn't find any problem, but I hope that Samsung 840 Pro Series SSD's will be more awesome than this one. Buy this SSD but don't expect any Extreme performance. Windows boot up in 9-10 Seconds..
