The 20nm 64Gb NAND uses a planar cell structure -- the first in the industry -- to overcome the inherent difficulties that accompany advanced process technology, enabling performance and reliability on par with the previous 25nm generation.
Additionally, due to their inherent advantages over traditional spinning hard drives, including better performance, lower power consumption, and increased reliability, drives made from solid state flash products should continue to gain in popularity as prices fall and capacities rise.
