No. RAID 5 distributes the parity across all the disks to prevent the
parity disk becoming overloaded with transactions (as happens with
RAID 3). In a 3 disk raid 5 stripe if a disk fails then you will lose
one third of your parity bits (but the other disks have the data) and
one third of your data bits (but the data can be reconstructed using
the parity)
You really really should go looking for some RAID basics - you are
misunderstanding how the various RAID levels work and how the data is
striped on the disks. It is leading you to say incorrect things.
