The Bottom Line The Western Digital MyBook Essential Edition external hard drive is a slightly pared-down version of the MyBook Premium Edition. It's a good option if you need additional storage without backup software. Western Digital's Passport Portable External Hard Drive lets you take a lot of data on the road for a low price. If write speed isn't a top priority, the Western Digital MyBook is a good deal at around $300 for a 500GB drive. It'll look good on your desk or bookshelf, too.
