Got this because of the recent End of the year sale on PlayStation vr games. I live in the country with no internet access so I have to travel between family to get access. In short if your like me and need to play games offline and can’t freely switch up your library on the fly this extra storage will really help. Oh yeah about the connection I have my powered ps4 stand running to my ps4 directly with my vr headset’s usb running to the stand, a usb Stick plugged into the stand and my hdd plugged into the ps4 directly. I know there’s issues surrounding the small amount of USB ports and it all works the vr headset is recognized, usb plays music all while I game and the hdd is recognized by the ps4.
