Test Read/Write speed in FreeNAS

Navigate using the ‘cd’ command into your zpool which is in the /mnt directory.

Run the following command to test Write speed
# dd if=/dev/zero of=testfile bs=1024 count=50000

Run the following command to test Read speed
# dd if=testfile of=/dev/zero bs=1024 count=50000

The first test will write a file called ‘testfile’ to your zpool and then the second test will read back that same file. You can change the count in order to change how large a file to create.
