Public bug reported:
I've recently purchased a 16GB USB flash drive. Under windows it has a
write speed of 5.2MB/s, however under Hardy Beta, it starts off at about
2.5MB/s after mounting, and gradually slows down as more data is copied
to it, either as a single large file or as many small files, whether
copied individually or in batches. I just copied a 4.4GB file to the
device and it took over two hours . Copying a similar 4.4GB file to the
device under Windows XP takes about 15 minutes.
After un-mounting then re-mounting, copying a 700MB file to it finishes
in under 10 minutes. Each time I re-mount the device, a new folder
appears under /media, which has the name of the flash drive with an
underscore appended. After mounting the device, then un-mounting and
re-mounting it twice, there are three folders under media, called
"UbuntuStuff", "UbuntuStuff_" and "UbuntuStuff__"
