| Re: file transfer speed...very slow
I found that turning off "Remote Differential Compression" sped up my file transfers significantly. You could try it by: Control Panel|Programs and Features|Turn Windows Features on or off|uncheck Remote Differential Compression. I have found no negatives to turning off RDC, and you can always turn it back on again. |

I also understand SP1 will be addressing this issue as well. |

| Re: file transfer speed...very slow
Hi, AJB. Your USB thumb drive is 2.0, right? And all drivers, hubs, and other components are 2.0? Since you are running Vista on this computer, I assume that your USB is all 2.0, but if you are using legacy hardware or software, it might be using the older, slower USB. |

| Re: file transfer speed...very slow
Hi, Actually that brings to mind a good question (I think). My computer was built with 14 months ago and I would assume all USB ports would be 2.0.... How can I check this is true for all the computers' USB ports (Front and back, etc.)? |

Possibly this has been suggested, but...I found that my file transfers both to external devices and within my hard drive were greately speeded up when I disabled Remote Differential Compression. You could try it by: Control Panel|Programs and Features|Turn Windows Features on or off|uncheck Remote Differential Compression. I have found no negatives to turning off RDC, and you can always turn it back on again. |

| Re: file transfer speed...very slow
The only quantitative test I did was a quickie test, consisting of copying a 1.91 GB folder from my main hard drive to a folder on an external USB drive. Results: With RDC turned on: 3:23 - three minutes and 23 seconds (using a stopwatch). With RDC turned off: 2:25 – two minutes and 25 seconds. So this quickie test reduced the copy time by about one minute, or a 33% improvement. Not sure it is a valid test, but interesting. I also am observing much faster file copy and move within my hard drive, remarkably so. The whole system feels faster. Note that I did not do a reboot after turning RDC off. I will leave it off, because even though my file transfers were quite fast before, they are even faster now. Will be interested to see your results. |

| Re: file transfer speed...very slow
Hi, AJB. The fastest drive in the world will be slow if it is plugged into a USB 1 port. That's why I asked about drivers, hubs, etc. And you didn't answer that part of the question. If you have a brand new motherboard with all USB 2.0 ports, but with an old legacy USB 1 hub plugged into your USB 2.0 motherboard port, with the new, fast, USB 2.0 drive plugged into the hub - you'll get only USB 1.0 speed. :>( Simply plugging that drive directly into the mobo, bypassing the hub, might solve your problem. The old "weakest link" analogy comes to mind. I could make other guesses, but I would just be shooting in the dark without knowing more about your whole USB "chain". |
