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.
