So I would have to disagree with you that WDC is the QUALITY leader. I just bought a WDC oem 8.4G harddrive and it makes the most noise and vibration of MAXTOR, FUJITSU, and WDC drives I have tried. My ranking for the three drives I have tried would be:
Noise is a big factor when buying and using a harddrive. I hate using noisy harddrives. I was the most satisfied with the FUJITSU 6.4G. It's very quiet. I was not very satified with either MAXTOR or the new noisy WDC. So I would probably buy another FUJITSU or try another manufacture (I haven't tried Seagate yet).
