To solve this kind of problems, oracle has created Oracle Hardware
Assisted Resilient Data (HARD) Initiative, and according to the

all large storage providers are members of this initiative, so smart"
storage does know about Oracle block format and can catch block
corruptions, before they are written to disk.
