    I recently got my t400 and transferring files to a USB drive goes around 7MB/sec while transfers go up to 20MB/sec on my friend's laptop. Is this normal?

    that sounds bit slow, which file are you transferring what sort of hdd do you use (i.e. capacity, cache size, and rpm) compared to your friends. In addition, are you running any softwares that constantly accessing the hdd.

    Not a T400, but my USB transfer rate is about 8-9mb per second on my T500 that I bought about 7 months ago. That seems about the same as my previous Dell laptops.

    Are you talking about the same file transfer on the same flash drive?

    I no longer have access to my friend's laptop, but transferring a RAR file with the same flash drive goes at 7.5 MB/sec on my laptop and almost 30 MB/sec on my desktop. My laptop uses 160GB 7200 RPM HD from lenovo, and the desktop uses a 640GB Western Digital 7200 RPM HD. I don't know of any software I have running that could be slowing it down, I reformatted the drive and did a clean install of Win7 after receiving it.

    The internal hard drive should never be the bottleneck for USB file transfers... it will always be either the USB drive itself, or, in the case of an external hard drive, the USB interface.
