My first hard drive was the Apple HD20 footprint of a Mac Plus by 3 inches high 20MB.

3200 64GB SD cards could fit in that volume.

3200 times the amount of data would fit on a single SD card's volume.

Capacity to size ratio improved more than 10 million times in 35 years.

It weighed 3.2kg. Enough of them would be over 10 tonnes to store what the 2g SD card does.

And it consumed ~30W. 96kW versus ~1W
