How about cstream?
http://www.cons.org/cracauer/cstream.html

It has nice features below:
* Exact throughput limiting
* Built-in data creation and sink (not using /dev/null and /dev/zero)
* Customizable reporting including bytes written
* Blocksize customization like dd

For example:

# cstream -t 10M -T1 -v1 -n 1G -i - -o /tmp/dummy1G
