Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

...and 3.75MB would have seemed like such a humongous amount of space back then too!

I find these kinds of comparison really interesting - seeing how far storage capacity has come and how tiny it is now for the amount of storage you get.

And the price is USUALLY very good per MB.
Not QUITE so good these daze cos of the RAM shortages pushing up prices beyond belief, but HDD's and flash memory still seem to be reasonably priced and not as insane as the RAM stick prices are.

I don't think I even knew how much memory the few mainframes had that I used (but "only" 50+ years ago).

I managed to get occasional access to a quite new minicomputer and it had a disk drive (in this case a fixed disk).  It really helped!

But it was... 64K (words, I suspect, which were 16-bit).  Actual memory (RAM) was smaller, 28Kw.

I don't know what it cost but it got an air-conditioned room :) something I think pretty much only computers and hospital operating theatres got back then (here, England).

1TB? Luxury! We used to dream of...

The drum store is so pretty though! And the micro SD is, providing you don't lose it as it's ejected across the room by the socket attempting to impart earth orbit velocity, so very boring.
