Iomega Rev & USB 2

I was wondering if anyone has any experience with an Iomeg Rev drive. Apparently everything works fine. I can mount, read and write to the drive. The problem is when I write a large volume of data to the drive, the drive slows to a crawl (and so does the computer for that matter, but CPU usage is more or less 0). The system load jumps and it takes several hours before the data is completely written to the drive and I can unmount it. It might be important to note that the backup application or whatever I'm using finishes a long time before the buffer is written to disk. I probably should be sending iostat output, but I needed to work on my computer today and it was last night that I last encountered this issue. This problem really makes the Rev drive unusable. So, I'm not sure that this is an Rev issue or USB 2 issue, but I've only encountered this problem Rev drive.

I find it unlikely that it's a USB2 issue, unless it's a problem with USB that's just recently been introduced in a new kernel. What kernel are you running? I use a USB2 enclosure for my 80GB IDE hard drive and I experience no slowdowns. I'm typically copying video captures or large MP3 collections back and forth between that drive and my internal SATA drive.
