NO, it cannot, apparently. I'm trying it right now and it's not working. Apparently the "USB Hub" part of it isn't making it play nice with the PS4. While trying to format it for extended storage I'm getting the error "CE-41899-1 > Connect the USB storage Device directly to the PS4." The best I can gather is that because it's a hub, the drive has an extra step to get through the hub part and to the actual external hard drive, something that the PS4 doesn't like.
