The Samsung SSD 840 EVO line-up is available in five capacities: 120GB, 250GB, 500GB, 750GB, and 1TB, as well as the three different kits (see above). For this review we had the 1TB model. The drive is fast, very fast and work's very well indeed. In fact it is the fastest SSD I have ever tried. There are a number of really great features with the drive too!
