The world’s largest hard disk drive, the Exos 20 Plus, will be unveiled in December


Rabindra Dhungel, 30 september 2020. US data storage company Seagate Technology has inaugurated the Data Spare 2020 conference. Through the conference, the company has announced that the world’s largest hard disk drive Exos 20 Plus will be unveiled in December. This internal hard disk drive will be the first HDD to use HAMR technology (which will increase the capacity of HDD) and MACH to actuator technology. It is designed to expand the storage capacity up to 50 TB by maintaining SLA performance.

Dave Mosley, CEO of Seagate, presented two interesting slides at the conference. On the first slide, storing one PB at 18 TB compared to eight TB showed that one-third of the TCO would be saved. In the second, 20 TB HAMR was compared to the 50 TB version and the cost per PB was compared. In the process, the fast and continuous use of a powerful hard drive with hyperscaler was also presented.






Seagate has already unveiled an open source S3 compatible Cortex as a software-based storage platform. There is also a referral architecture rack called Levy Drive that can deliver 106 drives (i.e. 2.12 PB) per rack node. Beginning in September, both Seagate and WD unveiled 18 TB hard disk drives based on CMR and PMR technology.
