As it turns out, Seagate’s upcoming HAMR HDDs are listed as Exos 20+, which confirms that the company’s first HAMR drives are set to feature a 20TB capacity. Over time, the company will also release HAMR HDDs with even greater capacities, but has not yet confirmed precisely how large these drive will be.



does not want to disclose capacities of its future Exos drives for competitive reasons, but usually capacity points are not considered as top-secret information. Further, customers of Seagate and Western Digital need to have an idea about upcoming capacities so they can plan effectively for the future.

Seagate’s upcoming Exos 20+ hard drives are expected to be drop-in compatible with existing 3.5-inch bays, which means that power consumption of the new HDDs will be lower than 12W.

The HDDs will feature a 7200RPM spindle speed, so sustained read/write performance of the drives will likely be higher than 261 MB/s, the speed of today’s top-of-the-range Exos hard drives. What remains to be seen is random read and write performance of the Exos 20+ HDDs, as well as their IOPS/TB ratio.

In addition to HAMR hard drives, Seagate is also preparing to launch its Mach.2 HDDs with two actuators. Seagate’s multi-actuator technology will double sequential read/write performance and significantly improve IOPS/TB performance of hard drives.

At present, select customers of Seagate are testing prototype HAMR drives, but capacities of these test drives are lower than 20TB.
