Hi,

I'm not finding any recent advice for sdcard or eMMC media, both of
which trigger the ssd mount option automatically. I seem to recall ssd
has had some optimizations recently, but haven't heard much about
ssd_spread.

While sdcard and eMMC are rather different, it seems they have two
things in common: they don't have the wear durability of even consumer
SATA SSD let alone NVMe, and also they both suffer from dog slow
writes. I'm unable to tell that ssd_spread does any better writes wise
on a Samsung EVO+ sdcard. So that leaves wear and in particular if
wandering trees is at all affected by ssd_spread?
