I am trying to decide which of these two hard drives to buy for my Ti 800 (40GB). I would like more hard drive space and am leaning to the 80GB, since I don't think it is that much slower than the 60GB. Has anyone had experience with this hard drive? A quiet drive is a premium for me. Thanks, Susan -- PowerBook 800Mhz, 1GB RAM 40 GB HD OS 10.3 HP Laserjet, 6MP, Epson R800
