iozone performs a large number of performance benchmark tests against a drive.
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.
iozone -a /dev/sda1
result:
Auto Mode Command line used: iozone -a /dev/sda1 Output is in Kbytes/sec Time Resolution = 0.000001 seconds. Processor cache size set to 1024 Kbytes. Processor cache line size set to 32 bytes.
