Over the years, the increase in mechanical hard disk capacity has been very slow, and there is a tendency to be fully overtaken by SSDs.
However, every quarter, Seagate and Western Digital will update their roadmaps and look forward to the development trend of mechanical hard disks in technology and capacity, especially Seagate.
SeaGate launches new cloud storage service
Recently, Seagate has announced a detailed future technology roadmap. It plans to reach about 50TB in 2026 and over 120TB in 2030. Mechanical hard disks are generally based on PMR (vertical storage technology) in recent years, but even after various optimizations and enhancements,
they have already approached their limits, and new storage technologies and mechanical structures are imminent. For example, Seagate’s HAMR (Heat Assisted Magnetic Recording), which has been developed for nearly 20 years, has finally blossomed. At the end of last year, a 20TB HAMR hard drive was delivered.
At the same time, the new Muti-Actuator structure has basically matured. The combination of the two allows The capacity of mechanical hard drives has reached a new level, and it will depend on them to reach 50TB in 2026.
Similar to the semiconductor process in the future, in order to achieve further breakthroughs, brand-new storage media and materials are indispensable. In this regard, Seagate also has long-term plans, first of all the so-called &ldquo.V
