Can anyone provide a management friendly low tech summary of the risks you may encounter if a database (seems to be configured in sys.databases) has either no page verification or torn page verification. The recommendation appears to be CHECKSUM. Please elaborate on the risks in using either none or torn page?

The risk of "NONE" is that potentially all data from certain table(s) is unreadable and thus lost.  You can't predict which tables it will be.  In short, NONE is just nuts.

CHECKSUM is more thorough, and helps you more quickly identify bad disk writes that are corrupting a db.
