dpr recently reviewed the WD My Passport Wireless also mentioned in this thread:
link. it will be my choice when traveling without laptop and usb drives.
This thread got me rethink what to bring on my trips. Since I read it, I have been trying different image file backup setups for laptop-less travels (i.e., smartphone interface only) over the last couple of months. Below are my observations:
- WD My Passport Wireless (mentioned by some here) is great but is heavier and bulkier than I thought. The 2TB hard drive is more than I need. This is a good tool for someone like my brother who shoots JPEGs and works almost exclusively with his iPad ... download his image files to his main computer once in a blue moon.
- Toshiba Canvio AeroMobile Wireless SSD is a great concept but poorly executed. The shock proof 128GB SSD is the right size for 2-3k DNG files that I typically have on each trip. However, the Toshiba Wireless SSD app from the Apple App Store is stuck in the interface design that is about 10 years ago. Third party apps (FileBrowser recommended by Toshiba) does not work well for transferring large files from SD cards to SSD. It's much slower than the Toshiba Wireless SSD app and the wireless network gets interrupted often. And the battery inside does not charge other smart devices.
- HooToo Wireless Hard Drive Companion + SD Card Reader + USB 3.0 Hub + 128GB USB 3.0 Thumb Drive: This setup does everything that the Toshiba Canvio AeroMobile Wireless SSD can plus providing 10400mAh multi-cycle backup battery charging capacity for my iPhone. Everything works well with the USB 3.0 high speed and the HooToo TripMate app is pretty easy to use. This is a great set up for those "off-the-grid" trips. The down side is the setup gets bulky with multiple devices to carry.
- RAVPower WiFi Disk (with a built-in SD card reader and 3000mAh battery) + 128GB USB 3.0 Thumb Drive: it does everything the HooToo setup does but in a smaller form factor (smaller than my iPhone). The battery inside can only charge my completely drained iPhone twice. However, this setup alone won't work for backing up Compact Flash cards that I use occasionally, but the HooToo setup does. The RAVPower WiFi Disk is a keeper for my upcoming multiple large city trip.
UPDATE: The RAVPower appears to be a USB 2.0 only. It's approx. 4 times slower than the HooToo's USB 3.0 setup above.
The above setups cost $100 to $150 each. In addition to the image files backup, I've got to offload/backup my iPhone data and stream videos and music by multiple devices wirelessly and simultaneously. I am all set to go!!
Hope the above helps.
