Seagate plans to release 100TB HDDs by 2025/2026 using HAMR technology

Seagate's largest drive today is 14TB.



Read more about Seagate's HAMR technology and their planned 48+TB HDDs.

We complain about price/GB now.. can't even imagine what it will be like for data center markets

Honestly, this is a great step forward in HDD technology but my only concern is reliability since gigantic drives like this would only be [logically] used for data centers and archiving

HDD reliability is only really an issue of running costs for most data centres of any sort. Drives are expected to fail so there's generally several layers of redundancy (Most larger places will generally try to keep data on at least a couple of different geographical locations incase of a major incident at one location).

If a drive sacrifices say 10% of it's running time/reliability for a 20% increase in price/GB and density then it's worthwhile, if it's the other way round(Or equal really given the costs associated with more frequent maintenance) it's not, but that's about as far as the real world effects go.

Additional benefit is also rack space. If you can run same capacity server in 3x less space it does lower running costs significantly (the main selling point for Nvidia Tesla servers over conventional ones). Will it equal out with reliability/cost per GB remains to be seen.
