SSDs instead of SAS.

If you are doing anything that will read from disk, SSDs will improve your
performance. If you are doing any reads from disk that are non-sequential,
SSDs will really increase your performance.

However, make sure you do the reading on the SSDs you're going to purchase
because not all SSDs are created equal. I had a client buy some smaller
OCZ-Vertex 3s recently which have a wear leveling issue (the 120GB drives
have fewer chips than the 240GB drives) that causes performance to fall
apart pretty quickly.
