Is there a noticeable difference between a 5400 rpm and a 7200 rpm hard drive?
It depends on the drive and how you use it. Are there two or three that you're comparing? What kinds of things do you do with your computer (e.g., lots of restarts, random access, sustained access, etc.)?
I'd suggest you get a 320 gig 5400 rpm drive for your uses. Cheaper an a lot more storage space. I have the Samsung 320 in my MBP and it is plenty fast for my work, which is similar to yours.
Thanks for all the responses. I'll get the 320gb 5400.
Do you have a cloning strategy in place? Sure makes troubleshooting easier, should a problem arise.
if you can live with 200Gb (or 320Gb if you get the latest Hitachi), I guarantee you that 7200 rpm is the right choice.
This might help you. I just bought and performed an upgrade for my macbook. After days of searching I ended up replacing my 80Gb 5400rpm for a 200Gb 7200rpm. I almost decided to go for bigger space rather than rotation but here comes the shocking news : the fast drive consumes less energy and there is a very noticeable performance increase.
