Price Drop. This 3 terabyte drive is a great way to back up SD cards when travelling. You plug an SD in the slot and it backs it up onto the drive. We used it for photography but it would also work for backing up video or anything else. Works great with either windows or Mac, but I can't get it to work with my new M1 Mac. This is apparently a known issue but WD hasn't addressed it yet. So if you're using a pre-M1 Mac or a windows machine this would be a good buy. I'm also including the protective case which I bought separately.
