And Audi is just Volkswagen. Except it isn’t (Audi tech shows up on VW when it reaches economies of scale, eg DSG gearboxes ~12 years ago)

Is HGST still a separate department or “just” their luxury brand now?

It's still a separate factory making separate drives. This line even uses a different storage controller. But this is also true for luxury ranges, in general, so you may be asking for too fine of a distinction. (Their usual luxury range is the WD Red, however.)

Which is why I asked. That sounds like the sort of thing that happens when it's just a label instead of a division.
