Kanguru Releases First FireWire Flash Drive 55

Posted by timothy from the and-firewire-is-like-a-hot-wire dept.
hajmola points out this Mac Observer article, which starts "At long last, after years of USB having a corner on the flash drive market, Kanguru has announced its Fire Flash FireWire flash drive line. With capacities ranging from 128MB to 1GB, the Fire Flash is the perfect way to carry your data with you, and since they uses FireWire, you won't be waiting around for the transfer to finish.""

          True (though it uses a different, backwards compatible, 9 pin connector). Alas, the flash drive's specifications list its maximum speed as 400mbps.
          • Well AFAIK, the physical connector is unfortunately neither forwards nor backwards compatible between firewire 800 and firewire 400 although the electrical interface is. Therefore you can plug a firewire 800 device into a firewire 400 port and vice versa provided you have the correct cables (one with a 4 or 6 pin firewire end and another with a 9 pin firewire end)

        Yes, in theory USB2 can do 480Mbps. In practice [barefeats.com] it doesn't achieve that kind of speed, it's slightly slower than Firewire 400.

        When you recall that Firewire supports isochronous transfers and daisy-chaining, which USB lacks, speed isn't the only advantage.

        Clearly you haven't tried to actually use USB at those speeds.

        There is no question, as far as I know, that Firewire 400 provides better throughput than USB 2.0 in a typical environment (and most non-typical ones as well). Not just better, either. Significantly better. I can attest to this personally. A file that, via USB, takes 3 seconds to copy to the hard drive in my USB2/Firewire400 enclosure, only takes about 1.5 seconds via Firewire. (for those concerned about my testing methods, yes, these are smallish files for a reason. I don't want the drive's maximum to be taken into account. As long as we're only writing to the 8MB cache, we should be fine.

        Anyway, yeah. Ignore the marketing hype and look at benchmarks. USB 2.0 -- replacing the Mhz myth with the Mbps myth.

      Technically, but not really. USB 2.0 is 480Mbps, Firewire (IEEE1394.a) is 400, but due to latency and protocol issues, Firewire is almost always faster, often _much_ faster than USB 2.0.

      That doesn't even include IEEE1394.b, which is 800Mbps. Unfortunately, these devices aren't of the newer flavour of FireWire.

      You will also certainly find major speed differences in different sets of USB & FireWire chips & drivers, so you'd have to benchmark the things to find out for sure.

      • How exactly are you cheating yourself? USB 2.0 is more ubiquitous than Firewire, and is fast enough for most things. It's still a case of deciding what you need the most, speed or interoperability with many machines, as well as the fact that most Firewire devices I have seen are more expensive than USB 2.0.

          • You are absolutely right. For camcorders I really think Firewire is best, personally. The iPod, well, I personally don't like the design, but the speed you get probably *is* faster than USB 2.0 can handle (not sure if you mean MB or Mb, or another unit entirely). The hard drive, because of the bus methods between USB and Firewire, I would expect Firewire to be faster.

    That's nice and all (I prefer FireWire over USB myself), but it would be useless to me. The problem is powering the thing. Sure, 6 pin firewire ports are powered. But what about me? My computer has a 4 pin port (which I'm not happy about). So how do I use it? There is no power from the port. There is no plug on the device for a way to plug it into a USB or PS/2 port to get power. The only way I can think of is a firewire Y cable sort of thing I have. You plug the device needing power in one end, the computer in another, and then you plug the third end into a wallwart (not unlike the iPod's one). So much for portable.

    So as nice as this is, it's not for everyone. USB really is superior for this task because of this (IMHO). I have never seen or heard of an unpowered USB port. And if such a thing exists, I don't think it is up to spec because (unlike FW) I think that all USB ports are require to be able to power something (not pass-though ports though).

    Still, neat to see. Now if we could just lose the 4 pin FW ports. The connectors are bad enough on their own. Redesign it, and and power to it.

    • I have never seen or heard of an unpowered USB port.

      Funny you should mention this .. I was testing a USB key I bought for my wife, when I plugged it into the USB port on the back of my Mac's keyboard, I got an error informing me that the device was on an unpowered port.

      • Ah, but that is an unpowered *hub*. No rules regarding that. The parent is referring specifically to what comes out the back/side/front of the computer.
        • Exactly. While plugging it into a keyboard or something might not work, I could always unplug a printer or something and I'd be set. Not only that, but many computers these days (at least on the PC) come with like 6 USB ports on the back of the computer alone. There is almost always a powered port.

          Also, to the grandpart of this post, did the USB drive work plugged into the keyboard? It may have been an unpowered port, but I wouldn't be suprised if there was enough power to run the USB key.

        I'm afraid you're doing what most users do. You're relaying the error message you thought you saw, and not the actual error message.

        USB has negotiation built into it. Initially, a device gets a small amount of power, then it negotiates for more. If it requires more power than is available on the hub, it won't get it. The hub inside standard Mac keyboards doesn't have much power, so some flash drives won't work on it. I've used flash drives that worked on a mac keyboard and some that don't.

Not only do many computers not have FireWire ports, but some that do have the 4 pin version and the drive won't work there.
