3,600 RPM mini hard drive from Western Digital is 6GB in storage capacity and appropriately named, Passport. With it’s compact size, folding USB connector and rubberized protective sleeve this seems like a good idea. Might be a little late to market considering there are 4GB flash drives for about the same price. A clear advantage for Western Digital are the re-write abilities of a standard disk drive verse that of flash memory, but even then we’re looking at a million writes before WD pulls ahead in that feature category. Prices start at $129 right from the WD website.
