Western Digital (WD) is advancing its hard drives to incorporate Heat-Assisted Magnetic Recording (HAMR) technology, with a road map leading to mass production of 36 TB conventional and 44 TB shingled HDDs starting in 2026. The current demand for increased data center storage drives this innovation. Currently, WD produces up to 26 TB and 32 TB HDDs using ePMT technology. In addition, after 2027, WD plans to explore HDMR technology for even higher capacities, introducing a novel approach involving ultra-small magnetic dots that enhance storage density.
WD has announced a migration plan to advance to HAMR technology for high-capacity HDDs, with mass production set to begin in 2026-2027.
The introduction of Heat-Assisted Magnetic Recording technology will allow Western Digital to offer HDDs with storage capacities of 36 TB to 44 TB.
After 2027, WD will shift focus from HAMR to HDMR technology, which uses ultra-small magnetic dots to achieve higher data storage densities.
The demand for greater data center storage has prompted WD to develop new HDD technologies, significantly advancing their storage capacities towards 2030.
