Or those 100 CDs for cheap of which you could literally peel off the data(or whatever you peeled off :-)

Got a whole bunch from my SOs father, after like 7 tries I told him, he's answer yes "I never got them working".

Got like 10 2GB SD cards he gave me too, but I was prepared and they all were like non functional.

A gigabyte was a whole lot of data back in the day.
