I have been using my Macbook Pro for about 5 years, it was the first model with the Intel chip. The 100GB hard drive is starting to go and I'm ready to replace it. I went over to Cnet to see what looks good. Oops. There are about 2,000 products to choose from, and I don't even know how to determine compatibility with my laptop. What are the steps I should follow to narrow in on a new hard drive? This machine does a lot of heavy lifting: audio, video, and image processing, etc. My goals are to increase storage to 250GB minimum (pref. 500+), improve performance, extend my Macbook's life by at least 18 months, spend less than 400$, and easy home install (youtube videos look do-able). I can spend more if there's a good reason to; just wanted to make the question specific.
Follow-up: Is it a given that I should upgrade memory at the same time? (Currently at 2GB SDRAM)
