I made a lot of speesdtest whith calculating a route of ~500km.

Both
SD-Card  /storage/XXXX-XXXX/Android/media/net.osmand.plus/
internal   /storage/emulated/0/Android/media/net.osmand.plus/
did not differ significantly in used time, both ok with access read / write.

yes - but only with lastest versions. But the new phone was shipped with 
Android 12, so i don't need other updates.
Thanks for assistance, Peter
