I’ve been looking at a [U]Western Digital[/U] - [B]My Passport Essential 500GB External USB 3.0/2.0 Portable Hard Drive[/B]. What is the speed of this drive (5,400 or 7,400 RPM) and does it make a big difference? I have looked everywhere for this spec. My primary purpose is save my finished audio and video projects to an external drive. Would this be a well recommended drive, since I would like to have two, to be on the safer side?
The drive you looking at is USB powered so it’s more than likely not a 7200 RPM drive. It sucks that WD does not say what drive is being used or give detailed specs. Since the My Passport Essential USB 3 drives are available in sizes up to 1 TB I would guess they are using Scorpio Blue drives which are 5200 or 5400 RPM drives, depends on where you look. A fast 2.5 inch 5400 RPM drive will have sequential read/write speeds of around 60 megs per second. So more than twice as fast as USB 2. A fast 2.5 inch 7200 RPM drive should have sequential read/write speeds of around 80 megs per second. As I said above a 7200 RPM drive will most likely need a power brick so portability would suffer. If you can live with the power brick I’d just get a 3.5 inch external USB 3 drive as it would be faster. Newer 3.5 inch 7200 RPM drives should have sequential read/write speeds of 100+ megs per second.
