Superblock is always located before data

false
true

The superblock part describing a particular disk is

different on each array member disk
the same on all array member disks

The superblock part describing an array is

the same only on first and the last disks

Why earlier superblock versions can give you more information about a RAID?

because such superblocks are typically written to safe place
because when NAS detects a disk failure, it no longer updates superblocks on them
because such superblocks are typically not affected by a rebuild

Where are copies of superblock stored?

only on the first member disk in the beginning
on each array disk always in the beginning
on each array disk either in the beginning of the disk or in the end
only on the first member disk in the end

md-raid allows to create arrays without superblocks at all
