If you’re a photographer or videographer, it’s important that you back up your files right away. But with all the lenses, lights, and other camera equipment you need to lug around, carrying a laptop where you can offload your data can be an inconvenience. Western Digital’s My Passport Wireless is the answer to your prayers. This chunky but light portable hard drive comes with an integrated SD card slot, making it a great accessory if you want to quickly back up your data. You can also free up space on your tablet or smartphone by connecting wirelessly to this device and interact with your files with WD’s My Cloud mobile app. When connected to a computer, the My Passport Wireless works as a regular external hard drive, and when running on battery, it becomes a wireless mobile media server. The My Passport Wireless has a standard micro USB 3.0 interface for charging and data connections. You can charge the drive via a computer’s USB port, a standard wall outlet, or in your car (a car adapter is not included in the box). There’s an on/off switch and a Wi-Fi Protected Setup/battery status button on one side, and an SD card slot on the other, which can be configured to upload multimedia content automatically when you insert a card. On top of the unit are the power/battery indicator light and Wi-Fi status light. Unlike competing devices that only support the single stream setup of 802.11n, the My Passport Wireless supports the dualstream setup of the 802.11n Wi-Fi standard. This allows for faster Wi-Fi speeds, but at the cost of battery life. WD claims the battery should deliver around six hours of run time; I got around only five hours, which I think is adequate for most scenarios.
