What is inside?

Hi - looking to get either the My Studio or My Book for Mac (same once I reformat?) - curious - I cannot seem to find out which of the WD drives are in them (either 3 or 4 TB version) - is it the green drives? Blue? Red? Black?

Thanks.

Steve

P.S. - I did go to the document library - couldn’t cross reference a drive product # to the number scheme.
