EVGA H370 Stinger (111-CS-E371)
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.
