I plan on upgrading my Macbook HD, and I was thinking about purchasing the Western Digital Scorpio Black WD1600BEKT currently $55 on Newegg. I'm wondering how noisy it is compared to the default HD that comes with the Macbook... If it is quieter then that's great, if it's the same that's fine, but if its noisier I'd rather just go for the slower Western Digital Scorpio Blue WD1600BEVT 5400rpm. If anyone has this HD or similar, please share with me your experiences with noise and any other comments. Thanks in advance!
