This wonderful old hard drive was state-of-the-art in 1985. It has a capacity of 42 megabytes. That is enough space to store (just barely!) two copies of the raw file from which this picture was made.
You probably have one or two terabytes of space on the hard drive inside the computer you are using to view this picture — that’s 2,000,000,000,000 megabytes. This drive stores just 42 megabytes. But you have to admit: the old D5146H is much better looking.
