Seagate multi-actuator hard drives think two heads are better than one
by from Techreport on (#3B2S6)
Technologies like shingled magnetic recording (SMR), heat-assisted magnetic recording (HAMR), and microwave-assisted magnetic recording (MAMR) all promise to improve the capacity of spinning platter drives, but none of them were developed with performance in mind. While HAMR and SMR could indirectly offer better throughput by way of increased data density, large jumps in hard drive performance have been rare in recent years. Seagate says its multi-actuator technology could double hard drive performance while maintaining magnetic hard drives' advantages over SSDs in cost per storage unit.
