RAID Mode Introduction
RAID 10 (1+0) - Mirroring/Striping:
RAID 10 (1+0) employs both mirroring and striping like RAID 3 and 5, but stores data
differently. The data is striped across the first two primary disks and then striped onto the
mirrored disks. In other terms, RAID 10 (1+0) provides an exact copy of the two striped
HDDs, which creates a striping of the redundant data. Under most circumstances, a
RAID 10 (1+0) configuration consists of four drives, two primary dedicated to striping and
two drives mirroring the striped data. This configuration produces better performance
and reliability.
Combine/Large (BIG):
BIG combines all disks and creates one large capacity disk. When data is read, the system
assigns data to be saved to the first HDD. When the memory space of the first HDD is full,
it will continue to store data on the following HDD. Should data on the first HDD become
damaged, both disks will unfortunately be compromised. Although BIG mode manages data
more efficiently by using memory disk space, it presents a lack of data security.
