Here's a useful little device. The Axxen portable hard drive is the ideal backup solution for those flooded with a variety of memory cards. With each device demanding a specific memory card, you can see how these cards tend to pile up: CF I/II, Memory Stick (and its variants the Pro and Duo), SD, miniSD, xD, MMC and other formats.

Thanks to the various card readers present on this portable hard drive, you can backup data from those cards. What's more, it can also backup your hard drive over a USB interface. The portable hard drive is available in three different models: A-3500 (3.5" drive), A-2500 (2.5" drive) and A-1800 (1.8" drive).

No word on the pricing yet. Did I mention it's a very useful device?
