if I change my slog slice starting cylinder to be 4k aligned even
though slice 0 isn't?
some people claims that due to how zfs works, there will be
performance hit as long the reported sector size is different with the
physical size.
This thread[1] has the discussion on what happened and how to handle
such drives on freebsd.

Yes, but that's for a 4k rotating drive, which has a much different
latency profile than an SSD. I was wondering if anyone had a
benchmarking showing this alignment mattered on the latest SSDs. My
guess is no, but I have no data.
