    “IBM’s history website has more information about the drive.”…than the drive could have ever held…

    Today, a device with 6,400 times that storage unit’s capacity could fit in the space of a postage stamp. Amazing advances in the storage industry!

    . . .tough to get that sucker on a key chain!

    Oh come on.. who would ever even need 640K? 5 MEGS?? That’s more than you’d ever read.. it’s just an impossible amount of data.

    Well, you have to compare it to what they had at the time – and even then it sucked. The equivalent amount of information on punched cards would have taken 16 times less room.

    80 bytes per card -> 62,500 cards / 5 MB -> 4″ x 8″ x 0.01″ ~= 3 cu. ft.

    The device in the picture appears to be about 6′ x 4′ x 2′ = 48 cu. ft.

    OTOH, the drum had better access times.

    Coming soon! Terra bite thumbnails and softer computer chairs with built in toilets.

    1956! That was when I was born. As hard disks got smaller, I got bigger. Is this a Dorian Grey kinda thing?

    Agree that’s got to be a drum, not a disk.

    We stored a lot more data per bit then than we do now. Led to some really goofy coding but the more information you could cram into this limited storage medium the better a programmer you were. — Just remember Y2K.

    Also there were 5 and 6 bit bytes on some machines I used.

    Took a corporate level decision to buy more space on the system.

    As late as 1986 a drive the size of a washing machine with a removable pack that was either 6 or 8 disks held less than a half gig.

    Only two mp3 files? That’s the equivalent of one 45 record! Wow, who’s the lightweight music medium now? Er, I mean then? I’m not a time traveller. Honest!

    Then there was the interface electronics – another rack of tube gear.

    This much platter area could store about one petabyte these days.

  13. neuromodder says:

    It could store that picture of itself about 160 times. (if my math is correct)

    I was under the impression this was a drum drive rather than a disk drive.

    It’s all relative. Look at the size of ports on that giant USB hub… I mean, forklift.

    No wireless.

    Less space than a Nomad.

    Lame.

    It was all about IBM’s Into Airplane Experience.

    And how long would it have taken the attached computer’s processor to decompress those two mp3s and convert them into an analogue audio signal?

    • GeekMan says:

      Don’t forget the memory! If the information can’t be processed in real time, you’d need to page all that decompressed audio to RAM.

    • bcuda69 says:

      It looks like the data throughput is about 15 kilobytes/sec. So if it was read and processed in realtime, it would take about 5 minutes. I don’t see how it could have a 600ms seek with only one access arm operated pnuematically.

    in 1984 a winchester hard drive for the synclavier synth was about the size of a suitcase and still only 5mb

    In 1986 I bought a 1 gigabyte drive the size of a suitcase for $10,000. Now its hard to find a 1 gig thumb drive.

    This particular unit was being delivered to the New Zealand government.

    One of those things held a Top Secret cat video during a good stretch of the Cold War.

      In Soviet Russia, cat lols YOU!

      I know, I know, In 1985, that joke was actually funny. Lend me your time machine and I’ll run back and tell it to Reagan.

    If you work in the public sector, your office probably had one of these installed in the 60s to run your financial system. Then removed and decommissioned in the 90s.
