about the results of your experiment ;)
Generally 4K sector drives support emulation of 512b mode (via the
"Advanced Format" thing), so when accessed from the BIOS (which is what
GRUB does), they will look and smell like an old-school IDE drive. ZFS
internally is sector size agnostic, being ashift=12 simply means that
1<<12 is the smallest block you'll ever see in ZFS.
GRUB is another part of the concern.
I've heard of instances where ZFS pools with 4K blocks are misaligned
due to the bootblocks - this is discussed here:

Is this also a problem here?
