We speak to Rainer Kaese of Toshiba about the roadmap for standard magnetic recording on disk drive, the roadmap to 32TB, and what it would require to get to 100TB or 200TB
In this podcast, we take a look at the roadmap for spinning disk HDD capability with Rainer W Kaesesenior supervisor in company advancement for storage items at Toshiba Electronics Europe.
We speak about the most likely hard disk capabilities we can see in the next 4 or 5 year as we head into the 30TB and 40TB variety. Kaese talks about using shingled magnetic recording (SMR)– i.e. overlapping drive compose tracks– and microwave-assisted composes as we consider capabilities that head towards 40TB.
Kaese likewise discusses heat-assisted magnetic recording (HAMR), which would be essential to get HDDs into the numerous TBs of capability, and whether that can be accomplished at a cost-effective price-per-capacity
Antony Adshead: We saw 20MB in 1992, 20GB in 2002, and 20TB today. What’s next? How will HDD makers press drive capability beyond what it is presently?
Rainer W Kaese: Well, if we had 20MB, 20GB and 20TB within each 20 years then we need to have 20PB in 20 years and 20EB in 40 years. That’s a bit of a long reach, and most likely 20PB and 20EB on a single HDD is a method beyond what we can think about today.
If you take a look at innovations like DNA storage or coding on quartz crystals it’s not that far out, however it will not be HDDs any longer.
On disk drive as we understand them todaywe remain in the 20TB variety, and what we understand we can make in the next years for an affordable cost that individuals want to pay that matches the economics is something around 30TB to 40TB, perhaps as much as 50TB in the coming years.
We are sure this will come as an item. We aren’t sure precisely when. Our obstacle is to produce it at an expense level that makes good sense. That we are dealing with. The physics, the advancement is ended up. The innovation exists.
That’s crucial to believe of. We likewise have innovation readily available that might possibly cause a disk drive of 100TB to 200TB.
It is possible innovation and physics-wise. What we do not yet understand is whether we can ever make it for a sensible cost.
There might be a 100TB HDD in 5 years which might cost numerous 10s of countless dollars since
