Verify should at a minimum read all the data. Ideally, it would read the checksum blocks too to make sure they are still valid, but it might not. Rebuild should read all the data and write out new checksum blocks. It might also validate that it can read back the checksum. > My Highpoint RocketRAID 2320 and 2340 cards can be scheduled to perform > either verify or rebuild.

Ideally, verify would read the data and the checksum and so would ensure that all data can be read, even if one drive fails. If so, that would really be all you need to do periodically.
