I don't think so, at least not just yet. But they do pack more in the same amount of area. I think Samsung has been doing it and their price isn't cheaper.
SSD’s companies like Samsung, Intel, Plextor, and Others are building there next generation of SSD’s using brand new TLC flash nand. I have seen a few sites claim this will make them cheaper and more reliable. I am sure each company has their own claims about their drive. Has anyone tested/compared these drives, can you send me a link or review. I am interested in this new TLC nand and the future of consumer SSD’s.
