    So file transfers from my computer to my external dont seem to be very fast.....takes like 13 minutes to transfer 1.5GB.....and I thought USB 2.0 was supposed to transfer 480mbps??? I have a Seagate 160GB USB 2.0 HD and a Dell 9200 Inspiron...here is what my device manager is telling me:

    13 is slower than I'd expect, but it's faster than USB 1.1 would allow... So it's definitely working at USB 2.0.

    You average 16Mbps sustained transfer rate to get 1.5GB done in 13 minutes.

    USB 1.1 is 12Mbps MAXIMUM THEORETICAL BURST rate.

    480mbps is purely a theoretical limit. USB 2.0 never has been and never will actually transfer things that fast.

    Are you transferring a few large files or a bunch of little ones? Transferring lots of little files always has a lot more overhead. If my math is right, 1.5GB in 13 minutes is 15,384,615 bits/sec. Nowhere near the theoretical 480Mbit/sec USB2.0 us supposedly capable of, but definitely higher than USB1.1's 12Mbit theoretical maximum. Have you tried a different USB cable, a different USB port, or that drive on a different computer?

    I've been transfereing large pics, movies, and smaller pics, just general stuff.....I would have thought USB 2.0 would transfer much quicker then it does, but I guess not??

    I've tried all the ports on my computer (4) and no difference, havent tried on another computer...

    I just didnt know if USB Mass Storage Device (my external) is supposed to have the USB 2.0 enhanced next to it or not...

    No.

    If you want faster external transfers, get a firewire drive. Even FW400 is faster than USB2.0.

    :dunno: we copied about 85 gigs of stuff to an external drive (100GB sata drive in an enclosure with SATA and USB2) in under 20 mins a few days ago...

    Was it a few really large files? It's always faster to stream large files than small ones, as previously noted.
