As I have been posting about our plan to purchase a new computer, our research continues. Now we are back to square one - the choice between a laptop or a desktop for reasons of space in our living room. And we also need another external drive for archiving, the 1TB is almost full with the regular new photos and videos. The question is this - is a 4TB drive slower in access compared to a 1TB drive or is the access of the same speed? We have noticed that our 500GB archive drive was much faster than our 1TB although they are not on equal footing since the 500GB has its own power supply while the 1TB depends on the CPU cable.
