When you take lots of high quality pictures, it often takes a long time to transfer them over to your backup device. Multiple gigs of data is nothing to scoff at, after all. That doesn't mean, however, that you should put up with waiting 10 minutes for your photos to transfer. Help is on the way.
The Nexto OTG ND-2300 Xpress is a photo backup device that can transfer a full gigabyte of data from a CF card in a mere 50 seconds, which is 25% faster than the previous record holder. It can also accept data from UCB devices via the included port. The specs as to how much data it will be able to hold and what the battery life will be have yet to be announced, but you should be able to pick one of these up as soon as next week.
