Do you have usb2 port? Do you have ehci module loaded so it works as usb2?
if not...
I wonder if windows do not write-cache the USB drive. But if I'd put a
filesystem not supported by windows onto flashdisk, it would be jffs2.
is the ext3 mounted with 'sync' option? it's quite common when mounting
flash drives, but according to mount man page, it doesn't work for vfat, so
this may also affect the speed...
