Seagate 20TB PMR HDDs to ship before year-end

Storage firm Seagate provided an update about its HDD roadmap. In an earnings call with investors, CEO Dave Mosley confirmed that 20TB HDDs using conventional PMR technology will hit the market this year.

We expect to begin shipping 20 terabyte PMR drives in the second half of this calendar year. -- CEO Dave Mosley

Seagate is also working on 20TB disks based on SMR and HAMR technology. 20TB HAMR-based HDDs are already shipping, albeit in low quantities. According to Seagate, the laser-based HAMR isn't cost-efficient enough until 24TB and above.

SMR is a shingled version of PMR, it allows greater storage density but has a bad reputation among computer enthusiasts because of performance issues.
