Just found this short article on the BBC. Western Digital are apparently developing using microwaves to dramatically increase data density on 3.5 inch drives. I Mwonder if there will be a speed increas to go with it? It would take a long time to back up 40Tb with todays HDD speeds.

Darn it! I just cleared out my savings on 10TB hard drives!!!

Weren't we supposed to have HVD (holographic versetile disc) with the same form factor as DVD and BD that could read and write at the same time with something like 150TB capacity by now?

Do you remember Guy Kewney? He wrote in PC World in the UK many years ago. I can remember him justifying a ridiculously OTT 400Mb hard drive in PC World. This was about the time that BBC Micros and Sinclair ZX Spectrums came with 16Kb of memory and we were still using cassette tape unless you were rich enough to own a 5.25 disk drive. A 10Mb HDD was considered to be something very special indeed — for Personal Computer users at least. This was in the eighties.

The timeline on this Wikipedia page makes for interesting reading, and actually surprised me. 500Gb was introduced as recently as 2005 by Hitachi (GST). We reached 1Tb two years later, but progress appears to have slowed after that.

BTW I see that Guy Kewney passed away in 2010 aged 64.
