“We have the flexibility to offer multiple versions of 20-terabyte drives to meet customer needs, not only with HAMR technology”, Seagate CEO David Moseley told an investment conference in April. These consumer drives should hit the market later this year. Seagate is also working on SMR drives for hyperscalers, which have a higher areal density but slower write speeds.įor consumers, on the other hand, Seagate plans to mass produce 20TB drives utilizing more traditional PMR technology. The firm claims that HAMR will enable the quick introduction of 22-24TB hard drives as needed, though no timeline is yet provided. HAMR drives are already provided to select partners, and underlie Lyve, Seagate’s nascent cloud storage platform. “Volumes are small but growing through calendar ‘21,” Mosley told an investment conference in November 2020.įor enterprise and hyperscalers, the expectation is to supply drives primarily using HAMR (heat-assisted magnetic recording) technology. Only time will tell how quickly we arrive there.įor now, Seagate is focused on rolling out 20-terabyte drives. And while 2020 may not have been the year of 40TB, the prospect of mega-capacity devices remains on the cards.

While this may not match the rapid acceleration foreseen in Kryder’s law, a tripling in capacity across a six-year period is hardly shabby. Seagate launched its first 6TB drive in 2014 and its first 18TB drive just six years later. Increment jumps of two terabytes became the norm. Hard drive makers turned to adding platters to each device to boost storage capacity. The acceleration in areal density-the concentration of bits stored per square inch of media-slowed during the 2010s.īut progress didn’t stall. In the 2000s, Seagate chief engineer Mark Kryder foresaw reaching 40TB by 2020 and downplayed the long-term capabilities of solid state drives.įor HDD, the reality was a much bumpier ride. Seagate started talking seriously about the feasibility of reaching 20 terabytes as far back as 2013, according to CEO Dave Mosely.Įven that was something of a step back from previous expectations.
