Western Digital USB 2.0 External HD Speed Problems...

Discussion in 'Amateur Video Production' started by Frank McMahon, Aug 11, 2003.

  1. It's a 160 GB / 7200rpm -
    http://westerndigital.com/en/products/wd1600b008.asp

    Setup went perfect however I can't seem to get the speed where it should be.
    I am formatted as NTFS, the USB 2.0 is a PCI Adaptec DuoConnect with 3 USB
    2.0 and 2 Firewire ports (I have nothing in the other ports yet).

    I run a benchmark program on my internal Western Digital and get 33 MB/sec
    read write. Excellent.

    Run benchmark's on the external USB 2.0 drive and get Read 10MB/sec and
    Write 8315KB/sec

    Is this it? Should I not get like 33 MB/sec? I need to edit video and
    thought the USB 2.0 would at least be as fast as my internal.

    I installed all the latest XP Pro service packs, system is completely up to
    date on HD drivers. Also installed the latest Adaptec USB 2.0 card drivers
    (Enchanced Host Controler).

    I just bought the drive and can return it, but Western Digital tech support
    can't figure it out. All they suggest is download the latest drivers and
    that is what I have done.

    Any other options? Does it sound like there is a problem or is this all a
    USB 2.0 external drive can give? The system is a P4, couple years old and
    PCI slots should be fine I would think. Unless there is different speed PCI
    slots.

    Any help would be great...thanks!!

    Nope, looks about right (write) for USb 2. My Maxtor USB 2 drive benchmarks
    about the same, while my 3 firewire drives a little faster. Bye the way,
    your benchmark speeds are plenty fast enough for Video editing.
    {benchmarked my drives with Canopus free program raptor test).

    Plenty fast enough. You just have to be >4mb/s to be safe.

  4. How many MB/sec is 8315KB?

    Bye the way, if this drive is a combo firewire/usb2 drive, it will benchmark
    much faster if you use your firewire connection.

    Slightly OT but I had a Firewire external HDD running from a PCI Hercules 3
    port card. Running out of PCI slots and needed more USB ports, so I changed
    the card for a Combo USB/Firewire one (Kouwell, 3+3 of each). Now the
    Firewire drive will intermittently restart XP when accessed. Any
    suggestions gratefully accepted.

    Use the drive mainly as a repository of your main video content, and for
    writing finished avi's and mpg's to.

    What I am alluding to is that if you have overlay tracks also on that drive,
    then when you run transitions, transparency, PiP or anything else requiring
    dual or multi-stream, you need 2x or 3x 3.6MByte/sec - and you're not
    getting that. Indeed dual stream would appear to be struggling unless
    there's some other dynamic at work.
