3D NAND is something we started talking about two years ago when Samsung released their 850 Pro solid state drive which was the first consumer solid state drive to feature 3D NAND.  With the launch of the MX300 Series Crucial becomes the second company to use 3D NAND in a consumer solid state drive.  The drive is engineered with Micron 3D NAND technology, resulting in an endurance rating of up to 220TB total bytes written by leveraging larger NAND cells to deliver top-notch performance and prolong endurance. Furthermore, Dynamic Write Acceleration, a technology that uses an adaptable pool of high-speed and single-level cell flash memory,  enables faster saves and file transfers.  Compared to 16nm planar NAND, Micron's 3D TLC NAND triples that density.  This not only will help lower solid state drive pricing, but also enable higher capacity drives.  Currently the MX300 is only available in a 750GB capacity, which has a price of only $199.99.
