I got my bits and bytes confused . So assuming internal is SATA II , with a 3 gigabit per second transfer speed , and a 5400 RPM drive has a read speed of 100 megabytes per second 800 megabits then the connector is not the bottleneck , the drive itself is . That was the point I was trying to make . The internal vs external isn ' t about the connector , it is about the speed of the drive . You could hook up an external , 5400 rpm drive and see little to no improvement over the default internal drive . Now you pay for a 500 megabyte per second SSD external drive and you should see a pretty big difference . <| sep |> My grandpa is going to India in a few weeks and he asked me if I wanted anything from India . I said Hmm . I ' m not sure . He replied , How about a nice girl ? the amount of arranged marriage jokes I get doesn ' t counter the amount of times I ' m told not to date and focus on studies . Just a few more months till freedom . Few more months .
