I am also experiencing this bug.

Kubuntu 10.04 Lucid
Lenovo ThinkPad T61
OCZ Rally2 4GB flash drive, FAT32

It's taking over 30 minutes just to copy a 500 MB file.  I've also tried
copying two 1 GB files, and I don't even know how long that's taken.
It's crazy.  This drive's write speed is higher than average, but even
at a slow, average write speed of 5 MB/sec, copying 2 GB should take
less than 7 minutes.

I did some digging on Google, and I tried switching the flash drive to
the anticipatory I/O scheduler, but it made no difference.  I tried
using NTFS instead of FAT32, but it made no difference.

This is just plain crazy.  I can copy faster (meaning, normal speeds) in
Windows or in 8.04 Hardy or in Debian.  Something is seriously wrong.

** Summary changed:

- copying files to an usb pandrive is slow and slows down in time (Lucid Lynx)
+ Copying files to USB flash drive is extremely slow
