While traveling I am very cautious about image loss. I regularly switch memory cards to minimize the impact of defect cards. The only thing missing so far was a quick and easy mobile backup solution.
Since a cloud based backup is no solution due to the huge amount of data and service availability I was thinking of getting one of these image tanks. But I just could not get myself on spending 300€ for a mobile hard drive with a SD Card slot.

my mobile backup solution: smart phone + USB hub + sd-2-usb adapter + external USB HDD |
But finally I found the perfect solution:
- small USB hub with power supply (8€)
- a USB OTG (on the go) cable (3€)
- a SDHC - USB adapter (0€, came with one of my cards)
- my old 2.5" 250 GB external USB hard drive (0€, already there)
- my Samsung Galaxy S2 (0€, already there)
--> saved 290€ :-)
Now I can copy the content of my SD cards everywhere where I have access to 110V or 220V power supply!
Speedtest:
Copying a full 8GB SD card (Panasonic SDHC, class 10) from my Nikon D90 to the external drive took 12 minutes.
Some remarks:
- You need a smartphone with a USB host controler and USB OTG (on the go) support
- I use the regular file browser that comes with Android 4.0.4
- If you whant to use a external HDD you need an active USB hub with power supply
- The hub I got does not offer power suply fot the USB host (our smartphone), maybe there are others that could also charge the phone while it copies the data.
- Should also work with compact flash cards or memory sticks, just get the correct card-2-usb adapter
- Some posters on the net suggest to connect the HDD and the Card first to the hub, before connecting it to the phone (I do not know why. I did not have any problems during my test. But will do anyways, because why not?)
Final note of caution
I also read some post that talked about broken HDDs and hung up phones. So try at your own risk. Don't sue me! :-)
Cheers,
