Can an external drive slow down performance?
I recently connected a 1TB LaCie external drive wih a FireWire 800 connection to my iMac running Mountain Lion. It seems like I'm getting the spinning pinwheel of death a lot more often. What can be done to check out where the slow-down is occurring ? If it isn't the external drive, are ther ways of improving performance?
Thank you"
