-====== Benchmark - Disk Speedtest using iozone ======
-IOZONE will do benchmark tests against my /dev/sda1 with the help of iozone.
-IOZONE performs a large number of permance benchmark test against the drives.
-The output produced by iozone is very brief though.  The default command line option **-a** is used for full automatic mode, in which iozone will test block sizes ranging from 4k to 16M and file sizes ranging from 64k to 512M.
-Lets do a test using this -a option and see what happens.
-<code bash>
-iozone -a /dev/sda1
