In brief: Hard disk drives are set to become much larger in the near future, but getting there has proven to be quite a challenge for manufacturers like Seagate. The company has been transitioning from traditional PMR technology to HAMR, and after being quiet on that front for a couple of years, it looks like it won't be long before we see HDDs that can hold 30 terabytes of data.

Speaking of HAMR, Seagate has high hopes that it can leverage it to enable larger generational leaps in capacity when compared to the traditional perpendicular magnetic recording (PMR) tech.

According to Seagate CFO Gianluca Romano (via Tom's Hardware), the company has been relatively quiet on the HAMR front because it didn't feel like the first-generation drives were suitable for mass adoption.

Romano didn't say when exactly we can expect to see this new HAMR family of drives on the market, but judging by the company's most recent roadmap, it's safe to assume he's referring to the 2023-2024 timeframe.
This means that unlike Toshiba and others, Seagate plans to skip the microwave-assisted magnetic recording (MAMR) step and go all-in on HAMR and dual-actuator technologies.
