As well as supercharging HDDs, WD is also exploring ceramics and DNA storage
Western Digital and Sandisk have begun the process of splitting into separate companies, with the former focused on HDD and platform development, and the latter now all-in on flash products. Both companies recently held investor days, and while Sandisk teased a 1PB SSD and a flash replacement for HBM at its event, WD's focus was on how it intends to supercharge hard drive capacity within a decade.
The company's roadmap to the future of HDD technology shows a clear progression from energy-assisted Perpendicular Magnetic Recording (ePMR) to Heat-Assisted Magnetic Recording (HAMR) and ultimately to Heat Dot Magnetic Recording (HDMR), targeting over 100TB capacities.
