> I figured out that a 4k-sector drive with a traditional MBR can be up to 16TB, not 2TB.
But only for disks with 4096 bytes per LOGICAL sector and 4096 bytes per PHYSICAL sector; you can't find those drives on the market.
There is only 512 bytes per LOGICAL sector and 4096 bytes per PHYSICAL sector for sale, those are 100% compatible with current 512 bytes per sector drive, just are slower in some cases (so they have the same limits).
