I am looking at upgrading my ol' G4 Quicksilver and am looking at HD's. I am currently running the original 40GB drive which now only has about 4GB left of open space. Nonetheless, I am looking for something to help with speed, performance and obviously more storage. I was reccommended a Western Digital 160GB Caviar SE Ultra ATA 7200rpm Desktop Hard Drive for $99 by the guy at the store. Any insight, experience, comments appreciated. My budget for the HD would be no more then $100-$150 Thanks!
