However to build a complete product, it will still need to develop the suitable head, drive controller, and other electronics for its 40 TB drive, which will take several years. Back in 2018~2019 the company already achieved a 2.381 Tb/inch 2 areal density in spinstand testing in its lab and recently it actually managed to hit 2.6 Tb/inch 2 in the lab, so the company knows how to build media for 40 TB HDDs. To build a nine-platter 40 TB hard drive, the company needs HAMR media featuring an areal density of approximately 2.6 Tb Tb/inch 2. Today's 20 TB HAMR HDD uses nine 2.22-TB platters featuring an areal density of around 1.3 Tb/inch 2. "With HAMR technology, it allows us to jump in steps of 4 terabytes, 6 terabytes, or even 10 terabytes at a time." "As we approach the maximum useful capacity of PMR technology, each successive drive increases by 1TB or 2TB at a time," said Jeff Fochtman, Seagate's SVP of Business and Marketing at the company's Analyst Meeting. In 2030, the manufacturer intends to release a 100 TB HDD, with 120 TB units following on later next decade. To hit these higher capacities, Seagate is looking to adopt new types of media. This was revealed at its recent Virtual Analyst Event. In particular, Seagate expects 30+ TB HDDs to arrive in calendar 2023, then 40+ TB drives in 2024 ~ 2025, and then 50+ TB HDDs sometimes in 2026. Seagate's current top-of-the-range HDD features a 20 TB capacity and is based on HAMR, which not only promises to enable 3.5-inch hard drives with a ~90 TB capacity in the long term, but also to allow Seagate to increase capacities of its products faster. In the recent years HDD capacity has been increasing rather slowly as perpendicular magnetic recording (PMR), even boosted with two-dimensional magnetic recording (TDMR), is reaching its limits. And hard disk drives will continue to service the needs of mass capacity storage with the most optimal, total cost of ownership for the next decade and beyond." "We have drive technologies planned which will enable long term HAMR growth and a path to over 100 TB devices. "We can use our recent experience, productizing our 20 TB HAMR drive to translate from laboratory demonstrations to products, which puts us on track to deliver 50 terabytes by 2026," said John Morris, Chief Technology Officer of Seagate. This is all within the 3.5-inch form factor. In the coming years, Seagate is set to leverage usage of heat-assisted magnetic recording (HAMR), adopt bit patterned media (BPM) in the long term, and to expand usage of multi-actuator technology (MAT) for high-capacity drives. Seagate recently published its long-term technology roadmap revealing plans to produce ~50 TB hard drives by 2026 and 120+ TB HDDs after 2030.
