Samsung SSDs a right ashift size for ZFS pool?

Hello,
I'm creating new zfs pool (raid 1)
And I have 2x Samsung 860 evo 512GB

I know that proxmox like to write a lot of stuff to disks (my setup 45 gb per 24 hours average, all VM idling none of them writing to disks)

And I didn't find any satisfying result about ashift for ssd.
Is it right to set it to 9? If SMART report says the sector size is 512 bytes?

Or should I go higher like 12/13 for ashift?

Also If I create a pool with higher ashift would not it create a write...
