noatime & nodiratime will not make any noticeable difference for the transfer of just 1 big file, and a lot of people here reported that symptom... Besides that the problem arises with non-ext volumes too.

I don't know if is just coincidence or luck, but I had this problem with my 64 bits system, I reinstalled Ubuntu and replaced with the 32 bits version and the problem is gone... Now I can achieve stable 10+ MB/s with my pen drive and 20+ MB/s with my usb sata disk.

Just in case it is useful:
