Bug Description
A full install of ubuntu 10.10 to a usb stick as if it were a hard drive results in terrible drive performance. The benchmark tool in the disk utility will not benchmark the drive because it is too slow. A copying data gives 2mb/s read and write performance, but the copy takes longer than it should at that speed because the copy often stalls. When I had installed on a hard drive and copied data to and from this usb stick, I could get up to 15mb/s. I don't know what package to report as having the problem. Please let me know and I will attach the apport information.

I'm sorry to say that, but what you complain is very normal.
USB flashdrives are suitable for occasional use, but
not as platform for operating systems.
