Hard disks were born in 1956

Hard disks were created for the first time by IBM in 1956, half a century ago, at about the same time that I started to learn computer programming. The first model was called Ramac, and it was bulkier and heavier than a grand piano.

Personally, I was aware of the existence of such storage devices, but I never actually used one. Seeing the clumsy way in which they were transported by a tiny team of human workers, I imagine that these fragile devices were surely in a state of breakdown for much of their existence.

It's interesting to see that the familiar acronym "ram" existed already: random-access memory. This was an annoying term, because it gave the impression that the contents of the storage device were not in fact accessed in a strictly determined fashion, but a little like throwing a dice. That, of course, was not really true. The adjective "random" was an example of primordial IBM marketing buzz.
