    I'm finding that file transfer speeds to my external USB drives has become very slow. Just now it took 5 minutes to move a 170mb file from my desktop to one of my USB drives, and I think that's really slow! What might be causing the slowdown?

    How much empty disk space does it have? Is it a USB/USB 3.0/FireWire800/Thunderbolt drive? How old (the drive, not you)? Does it make funny noises?

    The 4 WD USB drives are less than a year old and all of them less than half full. No noises at all coming from them, and they are USB 2.0 to the best of my knowledge.

    I have begun to wonder if perhaps the problem might be the 7 port USB hub I have them plugged into. Might that be an issue?

    That's very possible.

    Is it possible to connect the "slow drive" in question _directly_ to the Mac?

    If so, try doing that. Do the transfer speeds improve?

    Well I will try that, as soon as I figure out which is the slow drive, there are four of them on it, but I'll give it a shot two by two. It could be the drive I was moving the file to, or the one I was moving it from.

    This is one of those cases where a slow "process of elimination" is required.

    I would start by disconnecting ALL of them.

    Then add one, another, etc.

    Also, be sure to keep HANDWRITTEN NOTES nearby, so you don't start going in circles….

    To take fishrman's suggestion a step further, I recommend post it notes. As you are testing the file transfers, put a post it note on each one after you have tested it with the results especially if they are all alike. I find myself too often getting to the end and realizing I couldn't remember which one is which.... Just my .02 worth.
