I found where it was claimed it doesn't work. This is the link.
https://askubuntu.com/questions/1007716/formatting-an-ext4-partition-with-a-16kb-block-possible
That is a few years old and things may have changed. I also saw similar
info elsewhere. I may try it just to see if I get the same output. If
it works, fine. If not, then we know.
Odd it would have the option but not allow you to use it tho. :/

I'd start with something like <br>
<br>
mkfs.ext4 -b 16384 /dev/sdX
<div><br>
</div>
<div>and see where it leads. It's *possible* that the SSD might
fight </div>
<div>back, sending the OS a response that says it doesn't want
to </div>
<div>do that.</div>
<div><br>
</div>
<div>It could also be a partition alignment issue, although if
you</div>
<div>started your partition at the default starting address I'd

<div>that one.</div>
<div><br>
</div>
