Accepted answer

Ich habe 4x 6TB Reds im Raid (3x 256MB Cache und 1x die alte mit 64MB Cache im Synology NAS). Also SMR und CMR gemixt, was im Raidverbund gar nicht so toll ist. SMR ist für Raid und ZFS überhaupt nicht geeignet -> rebuilds sind dann immer ein Risiko. SMR und CMR sollten sowieso nicht gemischt werden, ich hoffe WD hat hier eine Lösung parat und tauscht die Platten aus - im NAS absolut unbrauchbar.
