I still like tape. No B37 abends. No waiting for recalls from HSM and reduces the need for HSM recycling.
As long as only 1 open is required at a time and no one needs to browse/edit the dataset, I don't see any reason to store large sequential datasets on DASD. CA-1 reporting and ISPF panels give a lot of easily access to information, without the need to scan through tons of SMS data to get the same for DASD data.
