I run an unraid server so I have several large drives however I'm not a normal consumer.
I'm saying that 14-16TB ssds just won't be a normal thing for at least 20 years.
Once they are below £200 is when they will be considered mainstream and comparable to mechanical drives of today in terms of £/TB. I don't think that may ever happen tbh. In 20 years time cloud gaming and cloud storage is likely to have gotten to the point along with broadband that buying storage will be a thing of the past.
We will all be streaming from the cloud
You mean like we did with unlimited online storage via Streamload in the early to mid 2000's and gaming from the cloud like we did from 2009-2012 with On.Live? I think that ship may have sailed already
