USB Floppy Disk Drive RAID Array Under OS X 53

ohlssonvox writes "I believe this is the first USB Floppy Disk Drive RAID; I have never heard of any others. It was done using OS X. I would like to share this with the world. The world must know the power of USB FDD RAID!!! This is NOT an April fools joke, I just happen to be fool enough to make this on April fools."

    I would think this is an April fools joke, other than "because they can", why would someone make a RAID of floppy drives. Personally I'm getting very sick of this April fools business. With some things its obviously a joke (which are normally the funnier ones), but with other things it could go both ways (cool but pointless, or cool but this will never happen)

    Maybe this guy will build a wire structure that connects 10 floppies and handle. Then hold the structure and insert all floppies into properly aligned drives... Keep adding floppies to hopefully beat the speed of the IDE, then sell it.

    this guy's an idiot. Everyone knows that you should use RAID 5 (or 0+1) with something as unreliable as floppies.

    I think everyone's missing the real irony in that the iMac was the computer that dealt the first death blow to the floppy to begin with. Its taken Dell until this year to catch up w/ the down-with-floppies trend.

    But now it seems that Mr. Jobs and Mr. Dell were both wrong, as this user has proven that with a little imagination, even useless technology can be made into something ... okay, well, I can't stretch this. its still useless. But its cool. Gives me hope that people like this aren't milling about the street causing trouble.

      I know it has nothing to do with the floppy raid, which I plan on trying, by the way.

  • I'd love to see one of these using the 2.88MB format, but does anyone actually do a USB floppy drive that supports it?

    Meanwhile, I wish April fools was more about stuff like this than just making up stuff.

    • Well not on my Mac, but I've seen this setting in the BIOS of my PC (running Linux, what else?). Where are these floppy disks and why didn't they ever become popular? The setting was even available on my 486, when WordPerfect took like 30 disks (and one was always bad...).
      • The 2.88 format stalled mostly because of media price and slow pickup. Factories had been too well setup for the 1.44 drives and disks so that the new 2.88 was seen as too expensive (disks more than drives) by many people. Perhaps once the floppy broke the 1MB barrier, people didn't really think they needed much more, or they needed a lot more. Software started being distributed on CD and anyone with major removable storage needs turned to Syquest and Iomega. (Gee, and didn't that turn out well?)

        So, onc

        • 2.88 is DEAD; Yea, i once had a 2.88 flopppy drive, used to carry around a 2.88 floppy but never used it (nobody else had a 2.88 drive.) My only reason for having a drive was because routers at work used 2.88 floppies to boot (1.44 was too small to vit all the data ont0) now, the drive and floppies were gone. dumped them with my p-100 box.

      Qps-Que used to make an LS120-type drive which could write 30-odd meg on a standard floppy. I've been trying to find one for ages :/
      • No, the LS-drives can write 120 MB to a special, more expensive floppy but can also read and write regular floppys. My friend has an LS-120 drive in his Amiga. They are connected throught IDE, that's pretty cool.
      • Unrelated to, and years earlier than, LS120. The floptical uses a floppy-like head mechanism, except it packs the tracks much closer together. It does this by using an optical pickup to align the head, rather than the dumb stepping used by regular floppy designs.
      • It looks like the "LS-240" is the drive you're looking for. Most reviews are a couple of years old, but they do exclaim that it can fit 32MB on a normal old 1.44MB floppy. Thing is, you get one write, then if you want to change anything you have to re-write the whole disk, so it wouldn't work for RAID. Still, 32MB is a neat trick, especially if it's a raw size without compression.

        Mind you, if I said to one of my friends that I'd bought a superdrive, he'd never speak to me again. Flakey isn't the right w

    Perhaps a pseudo practical application would be doing the same thing except with CDRs. Considering the low price of media and burners and the unreliability of the media, doing a raid-5 with five separate CDR would allow for extremely fast, reliable and cheep storage.
  • RAID (original meaning):
    Redundant
    Array of
    Inexpensive
    Disks

    This brings a whole new level to the "I" in RAID.
    • Floppies aren't Inexpensive any more. They cost about a dime for the floppy, while El Cheapo blank CD-Rs also cost about a dime, and they're 400 times as large. I think I've gotten CD-RWs for about $0.50 on sale. And IDE drives cost about $1/GB as well.

      On the other hand, it's certainly Redundant :-)

  • Doesn't OS X support around 127 USB devices or so? He should snag over a hundred of the floppy drives, connect them all together using tons of hubs, stick in all the disks, and then see how it performs. A pretty zippy, and bulky, compact flash card!

    • If you took a look at the article you'd have seen that he wants to do exactly this in the next "version".
    • Apparently no one out at Intel has yet to get 127 devices actually connected all at the same time. 4 years ago after Apple's WWDC, apparently a bunch of drunk Apple engineers went back to the Apple campus and managed to get 127 devices connected to an iMac!

      Drunk Apple engineers managing to pull off what the brainiacs over at Intel (who own the USB technology) can't... even when sober!

      But who knows, this could all be stupid urban myth.
      • Well, I know they at least tried, I remember seeing pictures of all those devices plugged in. Now whether or not it actually worked, I dunno.
      • I used to work in Intel's server group, and we did a whole bunch of wacky things (like setting up an 8-processor Xeon with 4GB of RAM just to run Quake 3 when it first came out.) One of them was to overload the USB bus. Using every USB peripheral we could get our grubby little hands on, in Windows 98, we got just over 100 devices plugged in, seeming to all work. (I recall having seven mice, and nine keyboards, along with a couple printers, a few scanners, about a dozen webcams...) Our main problem was f

  • I wanted to make a huge RAID of USB flash memory "Keys". If it weren't for the worthless speed you get out of USB 1.1, it could be quite cool.

    Also, if you had a large number of USB Keys in stacks of long USB Hubs, it would be alot like iso-linear chips on Trek. :)

    Now, on a more practical, barely serious note, what about a device with a FireWire 800 interface, that uses standard or DDR SDRAM, holds a battery backup, and writes it's data to a physical drive (preferably external) when power failure occurs...

      You could use Wiebetech's firewire flash/microdrive keychain [wiebetech.com], maybe even on multiple firewire buses, but for size/performance ratios disk-only ipod-like units are usually going to win.. Daisy chaining them all around your monitor or something though would look cute :)

  • Remember those ads when the Zip came out, that featured a stack of seventysome floppies, towering and teetering? "You can store ALL THIS on one Zip disk!", they screamed.

    Just recently I was looking at 120GB hard drives and thinking, shit, that would be one huge pile of floppies. Nevermind how long it would take to read them all!

    Then I said, wait, what if each one were in a drive? Figure you can read/write an entire floppy in about a minute or two. The maximum sustained transfer rate on a hard drive isn't
