I stumbled upon this site that has reproduced a 1980 Ad. “The early hard drive ads” really made me look back from where we came in technology. The ad seems to boast about the performance and capacity of the hard disk which is really true at that time. In two and half decades the multitude of technology growth is evident, now even if you want you cannot buy a medium with a capacity of 18 MB unless and otherwise specifically manufactured. Probably another two and half decades later you or I might laugh at this same post.
