Oracle has a tool to test drives specifically for database loads kinds
called orion - its free software and comes with a good manual. Download
without registration etc at
http://www.oracle.com/technology/software/tech/orion/index.html

Quickstart

create file named named 'fusion.lun' with the device name, e.g.
/dev/sda1

Invoke orion tool with something like
<orion binary> -run advanced -testname fusion -num_disks 50 -size_small
4 -size_large 1024 -type rand -simulate concat -verbose -write 25
-duration 15 -matrix detailed -cache_size 256

cache size is in MB's but not so important for random io.
num disks doesn't have to match physical disks but it's used by the tool
to determine how large the test matrix should be. E.g. 1 disk gives a
small matrix with small number of concurrent io requests. So I set it to 50.

Another idea: pgbench?
