My BlackBook 250 GB HD is already full after only three weeks! Mainly due to Boot Camp, and installing all of the scenery for x-plane... Anyway, my question is about the hard drives Apple use in the MB, is it known to be a reliable unit? I remember on my old PB I upgraded the HD after about two years as it became noisy and I didn't want to risk it. I don't need to upgrade yet, I believe the current maximum that will fit is 320 GB, is this likely to go up in the future? Also, what make of drives are most reliable? I was thinking about Western Digital.
