Thumb drive ext2 slow write speed

[Bogdan Bivolaru]

Hello,
Here's an idea: try formatting the flash in a solid state file system. Here
is a list:
http://en.wikipedia.org/wiki/List_of_file_systems#Flash_memory_.2F_solid_state_media_file_systems

I'd try my luck with JFFS2 or YAFFS1 or YAFFS2, as they both seem to be
free. I Have no hands on experience with solid state file systems though.
