After more than three years, the popular Samsung 850 Evo and Pro sata-ssd's finally get a successor. Samsung introduces today 860 Evo and 860 Pro, combining a new controller with brand new 64 layer V-NAND memory from their own factory. Is there still room for innovation in the field of SATA SSDs, or have we reached a stalemate?

The design of the Samsung 860 Evo and 860 Pro are hardly distinguishable from their predecessors. However, there are differences on the inside. For example, Samsung is making the transition to its latest generation V-NAND for both new ssd's, with 64 layers stacked on top of each other compared to 48 in the 850 series. This step in density results in lower production costs and higher capacities and is also very similar to what Crucial did earlier this month with their MX500.
