Hi, I'm purchasing the base model Mini and will be upgrading to a 7200 320 gb hardrive. I can purchase the 7200 Hitachi Travelstar today only for$69.00 Canadian. Since this is a one time thing, is this drive good enough or should I spend $30.00 to $50,00 more on a Seagate or WD. I've done a fair amount of research and read reviews but I would love to have some feedback from experienced Mini users. Thanks for any help.
