Introduction
JMicron JMB363 offers RAID level 0 (Striping), RAID level 1 (Mirroring and Duplexing),
RAID level 10 (A Stripe of Mirrors) and JBOD (Concatenate).
RAID 0 breaks the data into blocks which are written to separate hard drives. Spreading
the hard drive I/O load across independent channels greatly improves I/O performance.
RAID 1 provides data redundancy by mirroring data between the hard drives and
provides enhanced read performance. RAID 10 Not one of the original RAID levels,
multiple RAID 1 mirrors are created, and a RAID 0 stripe is created over these. JBOD
provides a method for combining drives of different sizes into one large disk.
Important
The least number of hard drives for RAID 0, RAID 1 or JBOD mode is 2.
The least number of hard drives for RAID 10 mode is 4.
All the information/ volumes/ pictures listed in your system might differ
from the illustrations in this appendix. And this mainboard supports RAID
0/ RAID 1 or JBOD mode only.
