| The Bottom Line | 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. | The Seagate FreeAgent Go is our favorite portable hard drive to date and takes our award for Editors' Choice. The drive is well designed and fast, and you won't find a better value for the price. | 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. | The Seagate FreeAgent Pro external hard drive is an elegant workaround for users who are intimidated by NAS drives. The bundled software is simple to use and makes copying your data to various location a cinch. We really like this external hard drive. | The SimpleTech Signature Mini Black Cherry is a compact, USB-only external hard drive that will tempt you with its sleek design, and then win you over with its capacity, performance, and price. |
