I have to admit that I'm a little confused by this option.

Doesn't the existing hardware (either the disk controller or the drive itself) already write a checksum during each write (on a sector-by- sector basis)? And don't the various system memories already have either parity and/or EDC (Error Detection and Correction)?

If so, then wouldn't the CHECKSUM option merely (but with significant overhead) duplicate that which is inherent to the hardware? So what's the benefit of a table-level CHECKSUM option?
