Okay I'm going to get my 2.53Ghz Macbook Pro tomorrow. I've been thinking about taking out the hard drive and putting it in an USB enclosure and then adding an SSD into the computer instead, in particular the G.SKILL SSD: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231221 I want to keep it in my Macbook, I may use it for downloading. It says it can last 1,500,000 hours (if MTBF is what I think it is). This means it can last about 64 years, which is more than enough. However my question is: If I use Mac OS, is it worth it compared to a 7200rpm hard drive? I've heard good things about SSD in terms of speed, however I have also heard of limited read/write cycles, and since Mac OS or Windows isn't optimized with SSD yet, is it worth is?
