As you can see, there’s no lvm striping; I rely on the software RAID
underneath for that. Both thick and thin lvols are on the same PV.
SSD typically do needs ideally write 512K chunks.
I could create the md to use 512k chunks for RAID 0, but I wouldn’t expect
that to have any impact on a single threaded test using 4k request size. Is
there a hidden relationship that I’m unaware of?
Yep - it seems the setup in this case is the best fit.
Sorry my typo here - is NOT ;)
