The Samsung 850 EVO is the latest in its affordable line of performance SSDs and shows Samsung's desire to push the solid state game along, even at the lower end of the price/performance stack.When it comes to solid state drives Samsung has really nailed its colours to the mast; it's going to be first to market with new technologies, it's going to aggressively drive pricing down and it's going to do it all alone.To that end, the Samsung 850 Pro was the first consumer SSD to arrive on the scene with 3D stacked memory making up its various capacities. The Samsung 850 EVO follows this trend, using another spin of the V-NAND technology for it's more price-conscious range of SSDs. And, as is its wont, Samsung is purely using its own technology - its own memory and controllers - for its drives.
