I found a very helpful site that had a lot of “tweaks” for Mac OS X users that have a SSD hard drive. There are several other places that have some of this information as well, but this site has them in a single post and an easy to read layout.

The recommendations for the Windows Virtual Machine are good too. Some didn’t run on my Virtual Machine that I tried (invalid command, etc) but still good info none-the-less.
