The Seagate 50TB HAMR HDD prototype has been completed, and a 24TB HDD will hit shelves this year

After each quarterly financial report is released, Seagate will publish the HDD capacity planning roadmap in hand, which indicates that 22TB and 24TB HDD will be launched this year.

From the Seagate HDD roadmap, it can be seen that it will advance in two directions, one is traditional magnetic recording CMR, perpendicular magnetic recording PMR and gravel magnetic recording SMR, and the other is HAMR heat-assisted magnetic recording, both directions will with MACH 2 dual magnetic arm technology.

Seagate plans to launch a 22TB CMR / PMR HDD capacity in the first half of this year, which will be packaged with ten disks, with a single disk capacity of 2.2TB, and a 24TB SMR HDD. However, this direction seems to end here, and indeed it is quite difficult to increase the capacity significantly.

The other is the highly anticipated heat-assisted magnetic recording HAMR technology that has been vigorously promoted by Seagate. Of course, it will also be matched with MACH 2 technology. Although this series has been transportation for many years, it has been evaluated, and the number of transportation and application scenarios is also very limited.

Seagate plans to release a HAMR HDD with a capacity of 30+TB in Q2, and this time it will be commercially available on a large scale, but it should not be within this year, and it is expected to form a sufficient scale around 2025. Seagate will increase the capacity to 40 + TB by then, and even 50 + TB HDD will be seen in 2026.

Seagate revealed that the prototype of 50 + TB HAMR HDD has been completed in its laboratory, and will be transferred to the prototype stage when the time is ripe.
