    Latest MBP 2.8, 17". I migrated iTunes library to this new Mac from my MAXTOR FireWire/USB 2.0 External Hard Drive. The USB was CRAWLING. 25 GB of info transferred to the Mac in TWELVE hours!!!

    What am I doing wrong?

    I thought USB 2.0 was somewhat faster, maybe not as fast as FW, but close to it...

    :confused:

    Nope, USB is pretty darn slow for sustained file transfers.

    25GB taking 12 hours is a bit excessive...

    I can transfer 50GB within an hour via USB 2.0...

    I don't believe you are doing something wrong
    But clearly something is amiss

    Have you tried moving anything else
    I seem to hear more problems out of iTunes libraries than anything
    Perhaps it has something to do with that

    I will be moving my iPhoto library today as soon as I get home.

    That one should be about 15 GB. I will be very sad if I leave again my computer working overnight.

    I also have a second hard drive. I will run some tests on both.

    I will check that too... I will give results this afternoon...

    Thanks!:D

    Firewire vs. USB:

    Found in an old post:
    http://forums.macrumors.com/showthread.php?t=454859

    "Firewire is peer-to-peer, the devices transfer directly to each other, meaning they can sustain a constant rate of 400mbps. USB involves the processor, which slows it down significantly and can't sustain that 480mbps."

    Also:

    "Generally speaking, FW400 goes up to that speed level and remains there for the balance of the transfer. Where as USB2.0 will spike a bit faster, then maintain at a level around 200Mbps.
    Real world, I have an external HD with both FW400 and USB2.0. I transfered some large files -- around 100GBs. The time required to transfer the files for USB2.0 was over twice as long as for the FW400 connection."

    USB is definitely slower than FW
    and FW 400 is clearly slower than FW 800

    Mystery Solved.

    15 GB transfered in 16 minutes.

    My bad.

    The problem was a USB hub that was in the middle of both devices. Direct connection and now I can appreciate it the speed of USB 2.0.

    I still miss FireWire.

    Thank you all.

    USB 1.1 is so very slow. I am always reminded of this fact every time I use my G3 iMac, but I always forget it within minutes!
