I'd start with something like

mkfs.ext4 -b 16384 /dev/sdX

and see where it leads. It's *possible* that the SSD might fight
back, sending the OS a response that says it doesn't want to
do that.

It could also be a partition alignment issue, although if you
started your partition at the default starting address I'd doubt
that one.

Anyway, I just wanted to be clear that I'm not worried about
write amplification based on my system data.

Cheers,
Mark
