Western Digital has revealed that the first commercial HDDs based on microwave-assisted magnetic recording (MAMR) technology will be released this year. According to one of the company’s slides, these will be 16 TB and 18 TB hard drives. 20+ TB drives with two actuators are planned for 2020+. As expected back in 2017, the first MAMR-powered drives will feature 16 TB capacities and will use eight platters, which was confirmed by the executive during the event. Western Digital’s 16 TB HDD will be aimed at nearline applications and are intended for cloud datacenters as well as enterprises that require massive storage capacities.
