What's the difference in Sector Size?

Creating Array has a menu for "sector size", what does it means? How the selection would impact in the performance of the unit?

This menu allows me to select between: 512B, 1k, 2k, 4k.

Modern/newer Advanced Format drives use 4K logical sectors & that's what you should be using in an array for them as well.

Which brand & model/part number drives are you (intending on) using?

I'm using Seagate Exxos 20TB. 5 drives of it for the Terramaster D5 T3
