      Absolutely amazing. You could actually swallow and pass a 500k device now with little to no discomfort. WELCOME TO THE FUTURE!

      Given 5MB was available in a 24" form factor in '56 www.research.ibm.com/journal/sj/422/grochowski.html (see figure 8). I think your info is wrong. The (I suspect erroneous) source seems to be Gizmodo www.gizmodo.com/archives/would-that-be-internal-or-extern...

      I recall in 1975 that a 55 MB disk pack was roughly 10 platters about 12" in diameter on a spindle. So there is no way this is 500KB.

      I agree with Iborsato... there is no way this is a 500kb device.
      A pretty good attempt at a hoax, I must say. It gave me a chuckle.

      And since when did the Oompa Loompas make computer equipment? I thought candy was their speciality.

      And yes Leo Laporte bought one these 5meg HD FH back in the day. Two weeks later the price of these drives drop 50% and seagate introduce their new 10meg at 20% less then original 5meg HD FH. hence this is the first leo effect in history!

      I would totally agree that this is a 500kb disk. Think about it, we're talking 1975. This was about 4 years before the Apple I. I remember laughing at an ad in 1994 about an add in 1988 with a computer housing a 20 MB hard drive. I believe several years before that, 5 MB was too much. Granted this was a main-frame type of situation, I'd still have to believe it. The guy has a pretty good account of the matter.

      The anecdote provided with the picture on Gizmodo says that this would have been a fixed-head HD with only four heads -- or only four tracks -- with which to store 500KB. The IBM site mentions 'actuator motors', suggesting a moving head and, presumably, more tracks and thus much, much higher data density. Moving heads would be more prone to error, though, especially in 1975, so I'm not surprised to see such a ridiculously huge piece of equipment.

      I think it looks like one of the new graphics cards that's needed to run Microsoft Vista.

      wow... that's pretty sad. imagine how much we could fit on a harddrive that size with today's technology. no one would ever need to delete anything again...

      you say that today ! - heh.

      This was the day of the 2314 disk drives connected to IBM 360 mainframes via selector channels. We used to tune IMS by visually inspecting the drives, memorex for us, and watching which ones tried to walk across the floor. A 2314 drive had 11 surfaces with a capacity of 29.2 million bytes. They came in 8 packs for a total storage of 233.6 million bytes at a cost of $256,400.
