Currently I have a Drobo 5N2 and using Seagate Barracuda Drives not the pro version. However one by one they all seem to fail. I have had 2 fails out of the 5 and one is now showing warning. I am not sure If i am using the wrong drives or is my Drobo the problem. I do photo editing and video editing off these drives. They also store the content I am working on.
