When shopping for external drives recently I noticed that the majority of the USB3 drives on the shelf were 5400RPM. I was surprised because I normally consider a 5400 drive to be ludicrously slow but USB3 to be pretty darn fast (those are the technical terms for it).If I'm looking for a drive that can handle reasonably fast transfers of large files (like system backups, movies, etc) at or around USB3 speeds, will a 5400RPM drive do the job? Or will it be the limiting factor such that I might as well use USB2 or pay the extra money (2-3x the price) for a faster drive?
External HD - 5400RPM over USB3 - Which is the limiting factor?
