I have a CCTV security system that saves to an internal hard drive. The user's guide shows how to take the system apart to replace the internal hdd if necessary.
My idea and goal: take the system apart and setup the sata hdd and while doing that, configure it with a second drive for external use - here's the thing - I'd like the second drive to be able to capture data/video at the same time as the first drive. Is that possible? I guess I'm looking for an "immediate" backup system. Can I do this? Or can I use the system's external USB port to somehow setup an external hdd for the same thing? Thanks.
