I've done quite a bit with IOzone, but if you're on Linux, you have lots of
options. In particular, you can actually capture I/O patterns from a running
application with blktrace, and then replay them with btrecord / btreplay.
The documentation for this stuff is a bit hard to find. Some of the distros
don't install it by default. But have a look at

for some "Getting Started" info.
