Using a short upgrade on the future of hard disks, Seagate has actually shared some fresh insights worrying launch of its next generation hard disks including its heat-assisted magnetic recording (HAMR) innovation. The business’s preliminary business HAMR hard disk is set to provide a 32 TB capability, most likely in the 3rd quarter of 2023, however the brand-new recording innovation will make it possible for a reasonably fast capability boost to 40 TB. On the other hand, high-capacity HAMR HDDs will co-exist with yet-to-be-released 24 TB and 28 TB drives.
The preliminary 32 TB HAMR-based HDDs from Seagate will depend on the business’s 10-platter platform that belongs to that currently in usage by the business and which has foreseeable yields and which gets rid of one prospective point of failure. Considered that the business will need to utilize brand-new media and brand-new compose heads with its HAMR hard disks, it is a sensible transfer to keep re-using as numerous tested parts as possible. That 10-platter HAMR platform will be utilized for 36TB, 40TB, and even higher-capacity HDDs moving forward, most likely with as couple of modifications as possible.
” When you go to HAMR, our 32TB is based upon 10 disks and 20 heads,” stated Gianluca Romano, Seagate’s primary monetary officer, at the Bank of America 2023 Global Innovation Conference (through SeekingAlpha). “The following item will be a 36TB and will still be based upon 10 disks and 20 heads. So, all the boost is coming through areal density. The following one, 40TB, still the exact same 10 disks and 20 heads. Likewise, the 50TB, we stated at our revenues release, in our laboratory, we are currently running specific disk at 5TB.”
Previously this year Seagate stated that it would ‘release its 30-plus terabyte platform in the June quarter,’ so anticipate these drives to enter hands and racks of hyperscale cloud company in the coming months.
Back in April the business stated it was delivering HAMR drives inside its Corvault systems for profits, nevertheless, the business refrained from formally revealing their capabilities and just suggested that they were based upon the 30 TB+ platform. On the other hand the business is delivering its HAMR HDDs for certification to hyperscalers, which will release them after they pass their tests.
In anticipation of the complete rollout of HAMR drives, some cloud company might decide to utilize Seagate’s 24TB HDDs, which depend on its standard perpendicular magnetic recording ( PMR) innovation with 2 dimensional magnetic recording (TDMR) checked out heads. Furthermore, some might even opt for 28 TB hard disks that utilize shingled magnetic recording. On the other hand, Seagate worries that these HDDs will be its last high-capacity nearline drives that utilize perpendicular magnetic recording.
” So, we have a 24TB coming out quickly, next couple of months, you will see it,” stated Romano. “That is the last PMR item. So I would state [higher] capability point above 24TB PMR, that is most likely 28TB SMR.”
