What about a hard drive with 4 kb physical sectors, but 512 bytes logical ones?

Question

ZFS

I want to buy such a hard drive , from the reviews it follows that the physical sector size is 4 kb, but it is displayed in the system as a sector of 512 bytes, and what value, in this case, should be specified for the ashift parameter for the ZFS file system: 9 for a 512-byte logical sectors, or 12 for a 4kb physical sector?
Those. Is it necessary to focus on the physical sector, or the logical one?
