For 3ware RAID controllers older than the 9690SA, two self-tests can be set: one to check whether UDMA Mode can be upgraded (applies to PATA drives only) , and another to check whether SMART thresholds have been exceeded. For the 9690SA, you can only check the SMART thresholds for drives. 7000/8000 series have the same internal schedule, but it is not viewable or changeable.
