But, when I recently broke open a Hitachi external disk (I needed the bare disk), it's the same as internal disk sold separately with 512b sector.  In fact, it's exactly the model that I bought almost a year ago, except for newer firmware which accounts for being 50% faster.  This may create problems when you take the disk out and connect it directly to SATA.

My external disks use whatever sector size the disk uses.

So with some newer WD drives the sector size is 4k, although presented
as logical 512byte sectors for compatibility, but performance suffers
if the system gets the alignment wrong.
