As every digital travel photographer, I am comfronted to the problem of storing a large number of images on a long trip. The cost per Mb of Compact Flash cards is getting lower and lower, but the files are also getting larger every time a new SLR is out.
Sometimes you can take your laptop with you and have ample storage size, but if you want to travel light, another solution is portable photo storage devices.
A number of these exist, in various sizes or features. The following tables synthesize the data I could find on this subject.
