    Lightbulb About USB Reading Speed

    I've been reading guides about USB HDD backups loading, and learned that backup discs run at 3X speed, original discs run at 6X, while USB backups loading speed exceeeds original discs.

    So approximately how fast does USB load ?

    Another question, say if a person is playing online (using backup discs) with another person (using USB HDD/original disc), will he/she experience glitches or lag in gameplay, because of different game reading speed ?

    Thanks for reading my question

    USB speed is approx 8x. And lag in online game play would be due to your internet connection/speed.

    Agreed. I have proven this by loading Wiiflow from my class 4 sd card and then loading same thing from my usb hdd. Usb is blazingly fast!

    I'm a little unclear. Was using your usb hdd faster than using your usb class 4 sd card?

    Your typical DVD at 3x speed is transferring data at a rate of about 4 MB/sec.
    Your typical HDD can transfer data anywhere from say...100 MB/sec to 3GB/sec or more. Though I doubt the Wii could ever process that much data that quickly.


    Don't quote me on any of this though. I'm just your average googler. :P

    Correct for the most part. A DVD can READ at about 8 MB/sec at 6x speeds, and about 4 MB/sec at 3x speeds. Modern SATA drives can transfer up to 6 GB/sec, depending on the SATA specification (SATA 1 is 1.5 GB/sec, SATA 2 is 3 GB/sec, and SATA 3 is 6 GB/sec), however, the main limiting factor in this discussion are the speeds of USB. The Wii uses the USB 2.0 specification, which has a maximum speed of 60 MB/s. So that's all that will be available to the hard drive.

    So, as you can see, the USB loader can *theoretically* load games 5-10 times faster than even the original discs, and 10-20 times faster than backup discs.
