hi there, so i just got the Airport Express Base Station so i can connect my WD external HD (i don't like to plug it directly into my laptop...) i also moved my iphoto library file to the external HD. why is iPhoto so slow to start up and do pretty much anything? i thought in this way i could save my internal SSD from clutter, but accessing the iphoto library from the external is driving me mad with its slowness. any suggestions? thanks!
