Digital images can be lost in a heartbeat: cards lost, corrupted or stolen and those precious holiday memories lost forever. Consider a back-up device that will allow you to copy from a memory card, independently of any other device. The Hyperdrive Colorspace UDMA 3 is a combined card reader, hard drive and screen. A simpler option is the Western Digital My Passport Wireless Wi-Fi Portable Hard Drive, which is a hard drive with an SD card reader and a rechargeable battery.
Both have Wi-Fi capability, so you can view your images with a tablet or smartphone.
