RAID 1+0

Index| Features| RAID 0| RAID 1| RAID 1+0 | RAID 2| RAID 3| RAID 4| RAID 5| RAID 5+0| RAID 6|


RAID 1+0 combines RAID 0 and RAID 1.
By configuring both technologies in a single array, both data duplication and improved access speed can be provided.

Although this combination makes installation more expensive compared to other technologies, both reliability and high I/O performance can be guaranteed.

Importantly RAID 1+0 on ETERNUS AF/ETERNUS DX provide extra protection. This is because a single disk failure doesn't prevent striping to other disks.
