i really need a new HD. at the moment i've just got the standard 30GB 4200rpm and it is really sllooooww. i've had a look at Mac Mall and all i could find were some 5600rpm drives. i'm looking for a 7200rpm HD, 30GB or larger,definitely not smaller than 30. does anyone one know where i could find one? i also only have 256 MB RAM, and i haven't shut-down for 3 days. could this have anything to do with the slowness? do Macs have to reboot like PCs to refresh the RAM and temporary files on the HD? i'm getting a faster HD and more RAM anyway, so whats the cheapest place to get them? i'm thinking that buying on-line from a U.S. site will be heaps cheaper than any store here in Aus.
