Hi AOG, I'd have said it's horses for courses. If you are wanting to permanently back up information/pictures, etc. I would suggest an external hard drive or CD-ROM/DVD disks. If you want to move information around from one PC/Laptop to another then the USB Memory sticks are the simplest, you can get ones that are password protected or encrypted. Memory cards are good but in my eyes they are more for mobile devices, i.e. digital cameras, mobile phones, video recorders. Hope that helps.
