Hello! I tried arc-23.12.16.img and lower, but work is not stable. After reboot or ac power loss DSM often not started, despite successful autorun ARC from USB flash. So i'm back to arpl-i18n (rr) by wjz304. It works stable with all stuations. Im using version 23.11.10. In configuration i select ds920+, 2 m.2 slots im using for cash of raid: 1st m.2 for 1st RAID-1, 2nd m.2 for 2nd RAID-1. All works perfectly.
