Many users complain that I/O Meter is too complicated of a benchmark to replicate results so my quest to find an alternative was started. Passmark has added several multi-user tests that measure a hard drives ability to operate in a multi-user environment.
The tests use different settings to mimic basic multi-user operations as they would play out on your server. Variances is read / write percentage as well as random / sequential reads are common in certain applications, Web Servers read nearly 100% of the time while Database Servers write a small amount of data.
The Workstation test is the only single user environment and will be similar to how you use your system at home.
The server and workstation tests didn't fair too well for the 9280-8E. We later learned that the LSI 9200 Series makes changes to the cache algorithm system based on how the controller is used. The observation time is longer than what the Passmark test takes to complete and makes the built-in self optimization nearly impossible for such short bursts simulating unique scenarios like the database test.
In the real world no one is going to run a database for only 180 seconds and the controller is able to optimize the cache for database files and run at a much higher speed. Hopefully we will soon be able to simulate these tests more accurately in the future.
