    usb fast enough?

    I'm pretty sure usb 1.1 is going to be fast enough to do mp3s... Is it going to be fast enough to play divx files etc? I already know it's not fast enough for DVD..

    I plan on using a 2.5 drive in an usb enclosure for a portable mp3 drive

    Re: usb fast enough?

    I would say so......

    do the math tho..... I have Austin Powers 2, approx 91 minutes in a good quality 700MB DivX 5 rip (which I did myself BTW)

    91 * 60 = 5460 seconds

    700 * 1024 = 716800 Kilobytes

    716800 / 5460 = 131.28 Kilobytes per second is required to keep this movie playing.

    as a rule of thumb I guess if you can achive 150-200K per second you should be in the comfort zone with that one. I have no idea on the max throughput of USB IDE adaptors - little help?

    the enclosures typically clame to get upto 900kB/s

    USB 2 units say 480 MB/s

    Too bad this thing doesn't have USB 2.0

    Oh yeah.. next time I'll try to think about things rather than waking up and with a stupid question in my head *^^*

    I use a USB 1.1 external hard drive, and the specs for it claim it can do 900KB/sec. I typically see arounf 600-700KB/sec, so it should be more than fast enough.

    i think i'm going to find a usb2 board that's small enough to fit in my case and buy a laptop dvd drive and hack a usb2-> laptop hard drive enclosure to make the hook up
