@Lauro: ...magnetic drums, tapes, cores, and discs...

Don't forget semiconductor magnetic bubble memory devices.

As an aside, I was once writing a test program for a small board from an aircraft that had an unusual chip package on it -- it turned out to be an 8x8 magnetic core memory in a square, chip-sized package.

@Lauro: ...there is only one prefix left, the "yotta," which was established at the 19th General Conference on Weights and Measures in 1991...

I best that back in 1991 -- which was two years before the Internet went public -- the folks who came up with the larger prefixes never expected that we would be talking about using the "yotta" in anger as soon as 2017
