EVGA Z490 FTW (122-CL-E497)
In the case of a drive
failure, the array controller
will notify you. When you
replace a failed drive in the
RAID10, rebuilding the
array is mostly seamless.
For example, look at the
array on the second row to
the right. P-Drive1 failed,
but P-Drive2 is still working
and uses the same data.
The array will pull data
from P-Drive2 during the
rebuild, so the array can be
used normally while P-
Drive2 copies ALL of its
data back to the drive
replacing P-Drive1.
The rebuild process will
only rebuild 1TB worth of
data because only one node
failed. There will be a
performance hit during the
rebuild process, which can
be further delayed if VERY
data intensive applications
are used, but overall
performance of the array
will still be fast enough to
run effectively during the
rebuild. RAID10 rebuilds
much more quickly than its
predecessor RAID0+1.
