I have an external USB 2.0 hard drive (buslink) that seems to not be running at its fastest possible speed in Suse 9.1. When copying large files from the drive, I get a maximum throughput of only about 1 MB/s. I had the same problem in Suse 9.0, and I had apparently fixed it by adding the async option to the entry in my fstab file. With that option, I was then able to acheive transfer speeds of up to about 7 MB/s. This seems to be true of any USB hard drive I use. The problem is that since there is no entry in the fstab file for the usb hard drive because of the new subfs system, I can no longer easily add the async option. I tried editing the hotplug.subfs.functions file to add the async option manually in there, but when I do so, it seems to not have the same effect as before (transfer speed is still slow). So, I have a couple of questions. First, why are usb drives so slow by the default settings in suse, and is there another way of achieving trues USB 2.0 speeds without adding the async option. I have not seen another way of doing it. Second, if async is the only way to go, why is it that this option no longer seems to have an effect within the new subfs system? Is there something else that I am missing here? I would think this would be a major problem, but I seem to see very little (nothing) posted about slow usb drives, so I kind of figure I am doing something wrong here, but I can't figure out what it is.
