Samsung gen 2 3D V-NAND SSD

Samsung, with this new 3D NAND SSD, you're really spoiling us ... or perhaps a rival?

We’re making it, but we’re not going to tell you much about it. That's more or less what Samsung has to say about its second-generation 3D V-NAND and the flash drives the tech is going into. As the name suggests, 3D V-NAND is made up of layers of flash cells stacked one on the other to increase storage capacity without …
