If you had multiple drives around the same age or from the same manufacturing batch, there’s a higher chance they fail around the same age. After one disk in the array fails, you can insert a new drive and rebuild the array, but during the rebuild, all your drives are in heavier use than normal operation. If you only have one disk redundancy, you’re vulnerable until that rebuild is complete.
Looking at the power supply listing, it says that it is USB-PD. It lists output as “5A @ 5.1V, 3A @ 9V, 2.25A @ 12V, 1.8A @ 15V”.
I fully admit that I don’t understand USB-PD, though. Does the Pi have to support it too?
