For my notes.. if you ever want to check the IO capability of a disk (local or network) on a linux machine, use the following command

\[bash\] dd if=/dev/zero of=test.file bs=4M count=1000 \[/bash\]

The above command make a copy of the output from[ /dev/zero](http://en.wikipedia.org/wiki//dev/zero?ref=kudithipudi.org) to a file called test.file (you can locate the file on the disk you want to measure) with a block size of 4M for a total file size of 4000Mb.
