http://communities.vmware.com/thread/197844 <- credit to this thread. compare your rig to real servers, ssd, san,nas, you name it. this job can crush dual controller SAN cache 1GB each easily.

I use the RELEASE version of iometer. but first craft your test.icf file. no cheating!
okay the test.icf file i'll post below:
the only thing you may have to adjust is the worker hostname (pc name) and the ip address to 127.0.0.1 and perhaps the drive letter
be sure to run iometer as admin; it will use tcp/ip to talk to its workers:
so you run iometer as admin; click on the WORKER 1 icon and go to the ACCESS SPECIFICATIONS and drags the idle,max,real,max through, random over to the left.
then run. it will take a while.
p.s. you can change the # of workers but i just left it at 1 since im not trying to emulate sql i/o at home.
