Seagate has packed 6.9 TB of space onto a single disk in the laboratory. This makes 3.5-inch HDDs with a capacity of 69 TB a possibility.
In a laboratory context, Seagate has achieved 6.9 TB of storage capacity on a single hard drive, according to ITHome. 3.5-inch HDDs with high capacity combine up to ten of such disks. With this breakthrough, Seagate opens the door for HDDs with a capacity of 69 TB.
This is especially important for data centers, where high density is an added value. The more capacity that fits into a single server and rack, the more appealing it is for the data center.
HAMR and Mozaic
Seagate further develops its high capacity on its HAMR technology. The company itself calls it Mozaic3+. Mozaic3+ is the collective name for various technologies that together enable

Seagate opens door for 69 TB HDDs with HAMR breakthrough
Seagate introduced HAMR and Mozaic3+ with the Exos M 32 TB, which, as the name suggests, has 32 TB of storage capacity. Even at the introduction of the technology, the HDD specialist indicated that HAMR was paving a new path, with even higher capacities on the horizon. The further development of Mozaic would make HDDs with capacities of 50 TB and more possible.
The breakthrough in the lab now shows that Seagate was not merely speculating. 69 TB drives in production will take some time, but they seem technically possible with HAMR and will likely appear on the market sooner or later. Seagate does not see 69 TB as the endpoint either. 10 TB per disk and more, leading to drives of 100 TB, 150 TB, and beyond, are on the agenda.
