Motherboard Manual CHAPTER 5: RAID FUNCTIONS 5.1 OPERATING SYSTEM Supports Windows XP, Windows Vista, and Windows 7. 5.2 RAID ARRAYS RAID supports the following types of RAID arrays: RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write times for many applications. RAID 1: RAID 1 defines techniques for mirroring data. RAID 10: RAID 10 combines the techniques used in RAID 0 and RAID 1. 5.3 HOW RAID WORKS RAID 0: The controller "stripes" data across multiple drives in a RAID 0 array system. It breaks up a large file into smaller blocks and performs disk reads and writes across multiple drives in parallel. The size of each block is determined by the stripe size parameter, which you set during the creation of the RAID set based on the system environment. This technique reduces overall disk access time and offers high bandwidth. Features and Benefits ­ Drives: Minimum 2, and maximum is up to 6 or 8. Depending on the platform. ­ Uses: Intended for non-critical data requiring high data throughput, or any environment that does not require fault tolerance. ­ Benefits: provides increased data throughput, especially for large files. No capacity loss penalty for parity. ­ Drawbacks: Does not deliver any fault tolerance. If any drive in the array fails, all data is lost. ­ Fault Tolerance: No. Block 1 Block 3 Block 5 20 Block 2 Block 4 Block 6

RAID supports the following types of RAID arrays:
RAID 0:
RAID 0 defines a disk striping scheme that improves disk read and write times for
many applications.
RAID 1:
RAID 1 defines techniques for mirroring data.
RAID 10:
RAID 10 combines the techniques used in RAID 0 and RAID 1.

RAID 0:
The controller “stripes” data across multiple drives in a RAID 0 array system. It breaks
up a large file into smaller blocks and performs disk reads and writes across multiple
drives in parallel. The size of each block is determined by the stripe size parameter,
which you set during the creation of the RAID set based on the system environment. This
technique reduces overall disk access time and offers high bandwidth.
Features and Benefits
±
Drives:
Minimum 2, and maximum is up to 6 or 8. Depending on the
platform.
±
Uses:
Intended for non-critical data requiring high data throughput, or any
environment that does not require fault tolerance.
±
Benefits:
provides increased data throughput, especially for large files. No
capacity loss penalty for parity.
±
Drawbacks:
Does not deliver any fault tolerance. If any drive in the array
fails, all data is lost.
±
Fault Tolerance:
No.
