When you think of a portable storage device, you think of something that can be plugged into a computer's port to provide extra storage space. Well, that's true for the most part, but some can offer more, such as really fast speeds, a lot of storage, a convenient backup solution or a built-in mobile media server that works even when not plugged in. Here are some of our current favorites that collectively offer all of the above, and then some.
Seagate Wireless PlusThe good: The Wireless Plus wirelessly adds 1TB of storage space to up to eight mobile devices. It can relay Wi-Fi Internet access and works well as a fast portable drive or as a robust mobile media server. The bad: It could use a faster Wi-Fi standard and its Seagate Media app doesn't natively support all popular digital video formats.
Buffalo MiniStation ThunderboltThe good: The bus-powered and affordable Thunderbolt HD-PATU3 drive offers fast performance via both Thunderbolt and USB. The bad: The Buffalo MiniStation has only one Thunderbolt port.
Seagate Backup Plus
