ImportantFor use within a RAID network, hard disks with different recording methods (CMR, SMR) should not be combined. When using hard disks with SMR in a RAID system, make sure that the RAID controller (or the NAS system) is compatible with SMR hard disks so that the partially blocked recording behavior with the SMR is not mistakenly labeled as “hardware Defect “to interpret.
