Sorry in advance for the long read I'm a photography hobbiest who recently went traveling. I didn't bring nor did I want to carry my computer with me so I was limited to the 16GB of compact flash that I currently own. On a DSLR shooting in RAW, this can fill up pretty fast. I guess the most logical solution today is to invest in higher capacity memory cards but they can be expensive and they never seem to be enough, especially as picture and video formats take more and more memory as camera technology progresses. I came across the HyperDrive iPad Hard Drive. It's pretty much a HDD enclosure that allows you to plug in memory cards and copy the contents to the internal harddrive. Problem is the enclosure itself with no harddrive is $250. Tack on an additional $50-100 for a 320-500gb 2.5" harddrive and that's a nice chunk of change that can go towards new camera gear, lenses, what have you. This brings me to the equipment part. I'm thinking of a card reader. In the back is a usb port where you can plug in any external usb harddrive that you already have lying around. You plug in your memory card, push a button, all the content is copied or moved to the connected HD and now the memory card is free to format and re-use. It would fit inside your camera bag or backpack. Something like this should cost somewhere around $20-30. Even if you have to buy an external portable HD, 500gb can be had for around, if not less than $100. That essentially gives you hundreds of gigabytes of memory for $30 if you already own a portable HDD, or hundreds of gigabytes or memory for ~$100 if you don't already have a HDD. Is a device like this something photographers/videographers would be interested in?...Or are you guys more prone to spending over $100 for a 64gb memory card? I originally wanted to design and make one for my own use (trips, backpacking, etc) but started wondering if I wasn't the only person who wanted something like this. Any input/feedback you guys have for me would be awesome. Thanks.
