I came across this today: Data Integrity Extensions, basically a
standard for have an application calculate a checksum of a block and
submitting it together with the block so that the disk can verify that
the block it is writing matches what the application sent.

It appears SCSI has standardised on a CRC-16 checksum with polynomial
0x18bb7 .


Not directly relavent to PostgreSQL now, but possibly in the future.
