This has been causing some confusion lately, so perhaps we could say:
ZFS checksums are at the file system block level, not to be confused with
the disk block level or transport block level.

Saying that ZFS checksums are at the file system block level is also confusing since zvols have checksums too. May be it is better to say that ZFS checksums are at the zpool block level because zpool is the place where all blocks either from file system or zvol are stored.
