Replying to Replace Optical Drive with SSD

My computer is running low on disk space, and I have been thinking about replacing my 320gb HDD with a solid state drive of some sort. But currently, the larger SSDs are pretty expensive.

Recently I stumbled upon this article, which explains how to install a SSD as a secondary hard drive, in the space where your optical drive is.

I can't seem to remember the last time I used my optical drive, and if I really need to use one I happen to have an external one laying around.

I thought this was a pretty cool modification, and wanted to hear some feedback on it. Should I try it?

Seriously, does anyone use their optical drive anymore???
