Western Digital reveals their X4 Four-Bits-Per-Cell NAND
Western Digital reveals their X4 Four-Bits-Per-Cell NAND
 Â
Western Digitial plans on showcasing this new NAND at the Flash Memory Summit (FMS) in August, with solid state drives and removable products being shown with this new flash technology.Â
One of the most interesting aspects of X4 NAND is that it is said to offer similar performance characteristics to their previous generation X3 TLC NAND. This is a big deal given the fact that QLC NAND requires 2x as many power states as TLC NAND, which should result in less performance and decreased reliability.Â
The most striking aspect in today’s announcement is the use of innovative techniques in the X4 architecture that allows our BiCS3 X4 to deliver performance attributes comparable to those in BiCS3 X3. The narrowing of the performance gap between the X4 and X3 architectures is an important and differentiating capability for us, and it should help drive broader market acceptance of X4 technology over the next several years.
