If this option is present, the client does not compute the MD5 hash of an object during uploads or downloads.
Using a known value of the CRC32C checksum can reduce the computation overhead of an object upload or download. It also provides better end to end integrity when the object data is obtained from a source that provides such checksums. Note that this option has no effect if the service does not return or compute a CRC32C checksum.
