I just got a new laptop today and when I saw the ssd it blew my mind. Most of my old drives are like the second from left and it's what I think of as a normal drive, buying a standard ssd still feels small to me. But look at that tiny thing to the right! It's the size of a postage stamp!
Assuming I managed to find the right specs (it is a Microscience hh-1050): The monster on the far left is from 1990, holds 40mb, read/write of 0.625mb/s, and weighs almost exactly 2kg. The baby on the far right I got in the mail today, holds 1tb, read/write of 5150mb/s, and weighs about 2.85 grams.
So we're looking at 25,000 times more storage, 8,240 times faster, and 1/700th the weight! And the one on the right is just 1tb, they make one that same model but 2tb. I can barely believe it exists even though I'm literally holding it in my hands.
In the compsci building at uni, there is a museum of sorts in the hall to the labs. At the beginning of the storage section, there is a 20Mb storage device. It is the size of a washing machine, I have no idea how much it weighs, but it has to be in the 100's of kg range.
Sitting on top are much more modern devices, 5.25"/3.5"/2.5" drives; I haven't been back for a decade to know if they kept going as tech improved.
"Sitting on top" is a brilliant way to display that.
Very effective.
The RAM section with the hand woven memory modules is so awesome. 1kb of RAM; tiny iron rings with fine copper wires threaded through them.
