As
you can see, the
difference between
RAID0+1 and RAID10 is
significant when looking at
how data is stored.
Although the drive volume
scaling and the level of fault
tolerance is the same,
internalizing the redundancy
can make a significant
difference overall to the
array.
In the examples to the right,
you can see that when one
drive fails the entire stripe
set fails; for a RAID0+1,
you would need to rewrite
3TB worth of data back
onto the failed node when
rebuilding, rather than 1TB
for the same drive count on
a RAID10.
RAID10 is the current
standard on Intel PCH
based RAID controllers,
largely because the fault
tolerance for it is a bit more
forgiving and the rebuild
speed is overall significantly
faster than its RAID0+1
predecessor.
