    Today's HDD collect and analyze functional and performance data to predict impending failure using SMART. In general, sector reallocations are expected, and many spare sectors are available on each HDD. If an excessive number occurs in a specific time interval, however, the HDD is deemed unreliable and is failed out.
    SMART isn't really that smart. One trade-off that HDD manufacturers face during design is the amount of RAM available for storing SMART data and the frequency and method for calculating SMART parameters. When the RAM containing SMART data becomes full, is it purged, then refilled with new data? Or are the most recent percentages (x%) of data preserved and the oldest (1-x)% purged? The former method means that a rate calculation such as read-error-rate can become erroneous if the memory fills up during an event that produces many errors. The errors before filling RAM may not be sufficient to trigger a SMART event, nor may the errors after the purge, but had the purge not occurred, the error conditions may easily have resulted in a SMART trip.
    In general, the SMART thresholds are set very low, missing numerous conditions that could proactively fail a HDD. Making the trip levels more sensitive (trip at lower levels) runs the risk of failing HDDs with a few errors that really aren't progressing to the point of failure. The HDD may simply have had a series of reallocations, say, that went smoothly, mapping out the problematic area of the HDD. Integrators must assess the HDD manufacturer's implementation of SMART and see if there are other more instructive calculations. Integrators must at least understand the SMART data collection and analysis process at a very low level, then assess their specific usage pattern to decide whether the implementation of SMART is adequate or whether the SMART decisions need to be moved up to the system (RAID group) level.
