Western Digital promises 40TB MAMR drives by 2025

Western Digital has announced the creation of the world’s first hard drive based around microwave-assisted magnetic recording (MAMR) technology, which it claims will allow it to scale standard 3.5″ hard drives up to 40TB.

Unveiled by Western Digital’s Mike Cordano during a presentation with MAMR inventor Jimmy Zhu, the technology is designed as a replacement for the heat-assisted magnetic recording (HAMR) system rival Seagate first demonstrated back in 2012.
