Firstly, there are a fair number of graphs. I want to
thank whomever it was that invented .png files. Not only was I able to

file size of all the graphs by 80% over using .jpg. Impressive. I have a few access patterns written to try and simulate
various loads. These are broken into three areas: general server, web
server and workstation. They aren't quite the same as other hardware sites
use but the differences are small. Here they are:

For the tests I take a queue (outstanding I/O's) and increase it to simulate increasing load upon the drive. Starting at 4 outstanding I/O's and increasing to 512 outstanding I/O's for an absolute worst case scenario. Let's see what the drives produce when these loads are applied.
