Seagate's financial reports show that it has been in mass production of HAMR HDDs for several years now , and it seems that the wait for these drives to appear at retail is finally over. The Seagate Exos product family achieves a capacity point of 30TB thanks to the use of thermal magnetic recording (HAMR) technology. The company spoke to the press last week about the Mozaic 3+ platform — HAMR's first high-volume platform — and how it lays the groundwork for rapid regional density scaling over the next few years. The new Seagate Exos 30TB HDDs use platters with an areal density of 3TB per platter, and Seagate plans to increase that by 20% over the next few years (compared to the 8% rate CMR HDD capacity grew over the last decade ).
The company Fax Lists noted that this quarter's volume migration will be to hyperscalers. Seagate observes that the average customer upgrading from a 16TB magnetic storage platform to new 30TB+ HDDs can nearly double the capacity of their server racks in the same amount of time because the new drives are interchangeable. This benefits TCO, especially in terms of power consumption. The company even calculates it - the average power consumption of the Exos X16 turns 9.44 W into 0.59 W / TB. The equivalent figure for the new Exos 30TB is slightly higher at 10.5W, but that means a 40% power saving per TB based on 0.35W/TB. The company emphasized that HAMR needed a number of other developments, grouped under the new Mozaic 3+ tag, to allow for the area density advancements that the new Exos family would allow.
These include: Plates using a new Pt-Fe alloy Writer plasma scientist 7th grade student of spntronics Integrated 12 nm controller The increase in area density is primarily due to the smaller grain size in magnetic media. However, legacy magnetic adsorbent media are not stable at very small particle sizes. Along with Showa-Denko, Seagate has developed a superlattic iron-platinum structure with increased magnetic coercivity to allow for accurate and stable data recording. The HAMR process requires heating the grain to change its state, and Seagate achieved this using a nanophotonic laser embedded vertically into the plasmonic writer subsystem. To penetrate smaller grains, the read head must also evolve.
