Hi guys, I've done a search on this but not really come up with the answers I need. I'm about to upgrade my Macbook from its 120GB drive to either a 200GB (for speed) or 320GB (for size) as well as the RAM from 1GB to 2GB. Is the difference in speed for the drive noticeable and worth the extra? I'm not bothered about heat or power consumption. I do use Logic occasionally, but not for anything high end. That said, would the slower speed do anything to audio recording/playback quality, or just access time? 200GB would see me through for a while, and by the time I need to do anything about another upgrade I'd think bigger drives at the faster speed would be available! However they're both roughly the same price, so if speed/quality isn't THAT noticeable, I may as well go for size and save myself some dosh later on.
