Hi all,
I've been searching for reputable information about this but have not had luck. Searching for "hard drive ECC" on google just gives a flood of results about ECC RAM.
It is my understanding that SAS drives can do on-drive parity-based ECC to recover from bit errors on the stored data (I'm not referring to data in-flight which I know is part of the SATA spec). Is that feature available on any SATA drives too, such as white-label Exos? If so, then that would reduce the usefulness of data scrubbing for detecting bit-flips in particular.
