I forgot to mention that fortunately, USB 3.0 is becoming more common and allows to draw more current.
The PCB can be the same, but it can be equipped with only the controller, PHY and connector required for the destination. No need for an adapter PCB, controller and connectors in the enclosure. Less parts = less assembly cost.Can you name a make\model, so I can avoid and don't recommend them,
No, sorry. The last time I opened a disk of this kind was several years ago.
