Optimizing an external hard drive
February 3, 2011 8:13 AM Subscribe
Let's say I want to buy a new external hard drive. I can pick a case with a particular interface (USB2/USB3/FW400/FW800/eSATA) and a mechanism with certain performance characteristics (RPM, latency, transfer rate, etc). Is there a straightforward heuristic that will tell me "if you're using interface X, don't bother buying a mechanism faster than Y."?

I do know that an interface's putative speed doesn't necessarily translate to effective speed—I've always found FW400 to be faster in use than USB2, even though the latter has a higher nominal throughput.
