Hello everyone, I'm new to everything CCTV so forgive my ignorance. My company moved into a building that came with the DM DS2 already installed, but with only a 320GB internal drive, and no external. Doing some research I see they want you to use their RAID Array and I was wondering if I could buy another brand of array/drives and use that, or if there was a way to just connect a Hard Drive or multiple Hard Drives externally. Any help would be greatly appreciated. Thanks in advance!
