I find this device so fascinating that I want to share it with you. This is a USB 2.0 dock for SATA drives. It comes with a power supply and USB cable. Your Mac or PC will recognise it as a standard external USB drive. Just pop in a drive and Bob's your uncle. Fill it with video footage or RAW pictures and put it into a safe after use. And it is only 32 Euro! Need more storage? Just buy another drive. Sorry for the rant
