Rather late for your propsed trip but none-the-less handy for others.
I have just returned from a month long trip to Vietnam and travelled with 3 storage devices. 2 4gb CF cards for my Canon and 1 250gig Vosonic VP5700 - http://www.vosonic.com/product.php?kind ... 3=0&id_4=0
This device is a laptop SATA hardrive in a multimedia enclosure; USB 2.0 external HDD, multi-card reader/writer. JPEG and RAW display supported (from selected DSLR cameras).
It also allows the playback of videos (handy for watching movies on the plane) and also has mp3 capabilities.
This gadget was priceless as it allowed me to shoot RAW for the entire trip and will serve me well in the future. In the meantime, I now have another 250gig hardrive.
