There is absolutely *no correlation whatsoever* between what 'track
and sector' is requested by the operating system and what physical
block of the SSD the data actually resides upon.

That is true, but if you get the alignment wrong then the data from a
single file system cluster may reside in *two* physical blocks, do you
not see that?

Sigh. You still haven't got it, have you?

*You have no control over that process*. The SSD is fully in charge of
making *whatever decisions it sees fit* vis a vis physical page and
block alignment.

It doesn't matter whether you place a partition on some arbitrary
boundary or not. The SSD will see a lot of activity in e.g. the
partition's inode and filename metadata areas and align that on a
physical boundary and move it around a lot, to take account of the fact
its a busy piece of disk.

is a decent read.
