I wrote a small benchmark program that will measure both read and write 
speeds for a file. A binary is available at (add a ".c" for the source).

Usage is: ./iospeed <file> <size-in-MiB>. Note that measurements with 
this program may not be valid on a jffs2 filesystem (due to compression) 
but it should be OK for SD-card measurements.

This thread on the Community list has some measurements from an 8G 
Sandisk card:
