Western Digital has introduced the industry’s to start with 20TB hard drives that integrates an iNAND UFS embedded flash travel (EFD) to boost efficiency, dependability, and ability. The firm’s OptiNAND architecture does not use 3D NAND memory for caching, but to store different metadata to increase vital characteristics of really hard drives.

Western Digital’s 20TB HDDs with OptiNAND know-how are dependent on nine 2.2TB ePMR (electrical power-assisted perpendicular magnetic recording technological innovation) platters, triple-stage actuator technological know-how for extra precise positioning of go through/compose heads, an iNAND UFS travel of unidentified capacity that takes advantage of 3D TLC NAND memory, and the company’s custom system-on-chip (SoC) that controls the push as well as conversation involving the HDD and the EFD.
