Podcast: 32TB HDDs By 2029, But How Much Bigger Can They Get?
ComputerWeekly, Wednesday, May 1st, 2024
We talk to Rainer Kaese of Toshiba about the roadmap for conventional magnetic recording on hard disk drives, the roadmap to 32TB, and what it would take to get to 100TB or 200TB
In this podcast, we look at the roadmap for spinning disk HDD capacity with Rainer W Kaese, senior manager in business development for storage products at Toshiba Electronics Europe.
We talk about the likely disk drive capacities we can see in the next four or five year as we head into the 30TB and 40TB range. Kaese discusses the use of shingled magnetic recording (SMR) - i.e. overlapping drive write tracks - and microwave-assisted writes as we contemplate capacities that head towards 40TB.
Kaese also talks about heat-assisted magnetic recording (HAMR), which would be necessary to get HDDs into the hundreds of TBs of capacity, and whether that can be achieved at an economical price-per-capacity.
