As you might guess, platter-drive-based models offer far more gigabytes for your dollar, but the flash-based ones are better able to survive jostling and bumps while operating. The WD Elements Portable 2TB External Hard Drive is perfect for backing up files on your PC for long-term storage or for when you're on the go. Measuring 4.3' L x 3.2' W and weighing 0.29lbs.

Unfortunately, no other manufacturer offers a product like the Time Capsule, which is a WiFi router with a built in hard drive.

If you already have another WiFi router, you might want to take a look at the Network Attached Storage (NAS) devices from Synology which will support Time Machine backups. In this type of setup, the Synology NAS attaches to your WiFi router using a permanent, wired Ethernet cable connection, which will allow you to back up over the WiFi router's wireless network.
