I had the chance to use a G5 for awhile lately and I was blown away by how snappy the machine felt. From watching the counters between my machine and the G5 I realized that it was disk access that was slowing down my Powerbook more than the processor. When I got my machine I didn’t bother to upgrade the hard drive to the 5400RPM drive. At the time the price didn’t seem worth it. I started poking around to see if there were any drive upgrades for the Powerbook that appealed to me. I had noticed over the past few months that everytime I upgraded a machine with a 7200RPM 8MB Cache Hardrive I felt a noticible improvement in the machine’s “snappyness”. I came across the Other World Computing website. There was a 60GB Hitachi 7200RPM 8MB 9mm ATA6 drive. I installed it this weekend and rebuilt my system. I have to tell you that I can absolutely tell the difference. The Powerbook is more responsive and just feels “as quick as it should be” ™. I highly recommend this upgrade for anyone thinking of eeking a little more performance out of their trusty Powerbook. The only downside (if you consider it one) is that it is slightly louder than the original drive. You’ll notice more of a whir coming from the PB than before, but nothing that would make me change my mind. I figured this might be the case seeing how it’s spinning at almost twice the sweet of the old drive! While I was rebuilding my machine I came across a great post that has a bunch of excellent OS X software on it. I’ve started using a few of the programs already! You’ll notice a Mac Software section to the linkblog.
