Hello, my Mac internal hard drive is 75 GB. I regularly use memory-greedy apps such as Photoshop and Illustrator to create and edit large graphic files. Also, I use Adobe Creative Suite 2 to design publications and will download CS4 very soon.

I use an external hard drive of 150GB to create and store all my working files, photos and music.

I've been told that I need to leave a certain percentage of free space on my internal hard drive for it to process optimally, but I cannot recall what that amount is. Is there a rule of thumb for this?

Right now there is only 19.7 GB free on my hard drive. Since I create and store all my files externally, I don't know what keeps eating up my internal hard drive space. Could it be application updates and upgrades?
