i just had a new computer built, asus p5ql pro mobo, 2.83 intel quad core processor, running xp sp3, and i bought an extrnal HDD that connects via USB to back up all my drives, but ****, the files are only transferring at 1 MB/s. transferring files from one internal HDD to another goes about 40 MB/s. i know the speed is limited by the USB but shouldn't it be faster than that?
