For a few years I've taken a netbook on each trip. Initially that helped with a lot of things like email/storing trip info and so on that are now done on an iPad. So the only reason I take the netbook along is to back up my images most nights. I don't edit whilst on trips, but the netbook gives me visual confirmation that the files are on there properly. I keep all images on the CF cards till they are safely on my desktop/external HDD at home. But with chargers etc its not a lightweight solution and I'm looking to save a bit of weight. What other routes can I consider. Has to be simple and accommodate holding up to say 70GB of data on a long-ish trip? My camera (5D Mk 111) has 2 card slots so I imagine I could buy 70GB worth of SD cards and record my photos in raw on both cards. I could I presume buy a portable and rugged HDD (eg LaCie?) and load images via a card reader/USB though I suspect that rules out visual confirmation. I thought I'd be able to use a tablet with a large hard drive which I could dedicate to that purpose but I'm struggling a bit to understand how to link the card to the tablet. A couple of tablet "experts" in retail have told me this isn't possible with CF cards. Any views on these or other options please?
