EVGA Z490 FTW (122-CL-E497)
o Vastly superior rebuild times compared to the previous 0+1
methodology of nested RAID.
•
Overall performance is good; comparable or slightly faster than RAID5.
The Bad-
•
Low space efficiency.
o With the capacity of modern drives, this will likely be less of a
consideration than in previous years.
The fault tolerance works a bit differently in RAID10 than in others because the array
has nodes with internal redundancy. In other words, although a four drive array can lose
two drives and remain operational, it greatly depends on WHICH two drives fail. If
both drives from the same node fail, then half of the data is gone and the array has
failed. However, every node, regardless of the number of total nodes, can suffer one
internal failure with no adverse effects.
