WD has also made improvements to the product’s companion My Cloud app for iPad. It also features a larger 6400mAh battery, compared to 3400mAh on the original model, which WD says can last up to 11.5 hours in the field, including 6 to 8 hours of operation under ‘hard use.’ Unfortunately, the USB port for connecting external devices appears to be of the USB 2.0 variety. The Pro version includes a faster SD card slot with transfer rates up to 75MB/s, up from 10MB/s, as well as upgraded 802.11ac Wi-Fi with speeds up to 20MB/s, improved from 9MB/s. The company told us that they received a lot of feedback from photographers following the product’s initial release in 2014, and that much of that feedback has been incorporated into the new Pro edition. This is the second generation of Western Digital’s My Passport Wireless series. It can also be plugged directly into a computer for standard operation. In addition to Wi-Fi, the drive includes an integrated SD card slot and a USB port that can be used to connect external devices, such as a CFast or XQD card reader. Western Digital has announced its new My Passport Wireless Pro hard drive, a Wi-Fi enabled portable storage device designed for photographers and videographers who want to backup, access, and edit photos or video in the field without using a computer.
