How do you match 32 terabytes of storage into a tough drive? With a HAMR.
Seagate has been experimenting with heat-assisted magnetic recording, or HAMR, since not less than 2002. The agency has sometimes popped as much as provide an indication or make yet one more “across the nook” pronouncement. The press has loved myriad possibilities to rejoice the wordplay of Stanley Kirk Burrell, however new qualification from large-scale clients may imply HAMR drives will probably be really accessible, to purchase, as bodily objects, for anybody who can afford probably the most magnetic house attainable. Third decade’s the allure, maybe.
HAMR works on the precept that, when heated, a disk’s magnetic supplies can maintain extra knowledge in smaller areas, such that you would be able to match extra total knowledge on the drive. It’s not simply placing a tiny scorching plate inside an HDD chassis; as Seagate explains in its technical paper, “your complete course of—heating, writing, and cooling—takes lower than 1 nanosecond.” Getting from a physics idea to an precise drive concerned including a laser diode to the drive head, optical steering, firmware alterations, and “1,000,000 different little issues that engineers spent numerous hours growing.” Seagate has much more about Mozaic 3+ on its website.

Drives based mostly on Seagate’s Mozaic 3+ platform, in customary drive sizes, will quickly arrive with wider availability than its preliminary take a look at batches. The driver maker put in a monetary submitting earlier this month (PDF) that it had accomplished qualification testing with a number of large-volume clients, together with “a number one cloud service supplier,” akin to Amazon Web Services, Google Cloud, or the like.
