RAID 10 (Stripe Mirroring) RAID 0 drives can be mirrored using RAID 1 techniques, resulting in a RAID 10 solution for improved performance plus resiliency. The controller combines the performance of data striping (RAID 0) and the fault tolerance of disk mirroring (RAID 1). Data is striped across multiple drives and duplicated on another set of drives.4 1.2 RAID Configurations Precautions 1. Please use two new drives if you are creating a RAID 0 (striping) array for performance. It is recommended to use two SATA drives of the same size.

RAID 10 (Stripe Mirroring)
RAID 0 drives can be mirrored using RAID 1 techniques, resulting in a RAID 10
solution for improved performance plus resiliency. The controller combines the performance of data
striping (RAID 0) and the fault tolerance of disk mirroring (RAID 1). Data is striped across multiple drives
and duplicated on another set of drives.4
1.2 RAID Configurations Precautions
1.
Please use two new drives if you are creating a RAID 0 (striping) array for performance. It is
recommended to use two SATA drives of the same size. If you use two drives of different sizes, the
smaller capacity hard disk will be the base storage size for each drive. For example, if one hard disk has
an 80GB storage capacity and the other hard disk has 60GB, the maximum storage capacity for the
80GB-drive becomes 60GB, and the total storage capacity for this RAID 0 set is 120GB.
2.
You may use two new drives, or use an existing drive and a new drive to create a RAID 1 (mirroring)
array for data protection (the new drive must be of the same size or larger than the existing drive). If
you use two drives of different sizes, the smaller capacity hard disk will be the base storage size. For
example, if one hard disk has an 80GB storage capacity and the other hard disk has 60GB, the maximum
storage capacity for the RAID 1 set is 60GB.
3.
Please verify the status of your hard disks before you set up your new RAID array.
