Price vs. Performance
I am shopping around for an external USB hard disk drive. When I compare
several models, most, if not all, specify the speed as "Up to 480 Mb/sec". I know this is a theoretical maximum but I am trying to ascertain what criteria to use to determine what the best value is. For example, I am interested in a 320GB drive. My laptop: Windows Vista Home Premium x64 Intel Core 2 Duo T9300 at 2.5 Ghz 4GB RAM USB 2.0 Firewire 400 connector Two 120GB 7200 rpm hard drives I assume that the data transfers will be limited to the speed of the slowest component involved in getting the data from source to target. The store geek told me that the fastest transfers would be achieved by the models supporting Firewire connections. Is Firewire 400 really faster than USB 2.0? Does the fact that the external hard drive spins at only 5400 rpm negate the connection speed advantages of Firewire over USB 2.0? Would a 7200 rpm drive make a difference or is the read/write speed irrelevant? |

Get the most space/rpms that you can afford... and USB will do just fine. Don |
