Need to back up a ton of files or a whole lot of video? You're in luck: Best Buy is currently selling Western Digital's easystore 4TB external hard drive for $90. It's a great price that's well below what you'd pay for this much storage elsewhere.
As you can see by the image, this is a desktop hard drive takes up a little more space than those portable external hard drives. (Best Buy's specs say it's 6.7-inches high by 1.9 inches wide.) The drive uses USB 3.0, which is standard these days for external drives.
This easystore drive is a little different from its counterparts in Western Digital's similar-looking My Book line. Exclusive to Best Buy, it appears to have a different set of included software. Both lines have the WD Backup utility, but easystore doesn't appear to come with Acronis True Image WD Edition for cloning drives.
