Most likely a WD160EDFZ or something similar. Got WD Elements and WD My Book external drives or Seagate Backup Plus. Seagate is nice as they have an USB3 Hub included allowing them to be cascaded.
But moved back to using a Docking Station and extracting the HDD's as a side-effect.
My 12 TB WD Elements drives (2020) extracted were WD120EDAZ models and before 10 TB WD Elements (2019) were WD100EZAZ models. Waiting for this years offer. HDD's in fact just got more expensive this year.

As strange as it may sound an External HDD including a housing, PSU and USB3 cable of the same size as an Internal HDD is far cheaper. Different vertical markets though as Internals are used by system builders and externals by the home customer.
For use with media players the quality is good enough. Putting those into a NAS running 7x24h is probably not such a good idea.
