Better off making something up. Flebibytes or something. Gibson should've done that in the original.

Or being deliberately nonspecific. Three memory modules, going cheap if no questions asked. That's why Snow Crash still reads so well, it skirts the quantitative and focuses on the qualitative.

That's why Star Trek used things like kiloquads. Unless and until you know what a "quad" is, it's just a number in mid-air.

Flebibytes? That's a crazy amount.

On the street, sure.

In academe anything under ten mangabytes is noise these days tho and I imagine the dark economy is two factors beyond anything we have access to. :/
