There are high failure rates for the 4TB version of this drive. After moderate use the drive can develop bad sectors which block file reads. Scandisk does not detect the errors and the data blocks are not recoverable. There are widespread reports of this problem but Samsung have yet to issue a statement. [Jul '23 SSDrivePro]
