  • Page 62 ACS-9910 User’s Manual The ACS-9910 can support the following RAID levels: 0, 1, 3, 5 and 0+1. Which is the right level for you? The answer depends on the application you use your RAID for. RAID Level 0 offers high transfer rates, and is ideal for large blocks of data where speed is of importance.

  • Page 63: Appendix B - Introduction To Raid Levels

    Appendix B – Introduction to RAID levels RAID 0 RAID 0 links each drive in the array as one huge drive. Storage capacity is determined by the smallest drive in the array. That capacity is then applied to format all other drives in the array. If using a 40 GB, 60 GB, and 50 GB drive in a RAID 0 array, your system will see one huge drive of 120 GB (40 GB×3).

  • Page 64: Raid 1

    ACS-9910 User’s Manual RAID 1 RAID 1 is commonly referred to as Disk Mirroring, Disk Shadowing or Disk Duplexing as all data is duplicated across both disks. As data is identical on both disks, storage capacity is that of the smaller disk. RAID1 has poor performance for write operations but very high performance for read intensive operations.

  • Page 65: Raid 0+1

    Appendix B – Introduction to RAID levels RAID 0+1 RAID 0+1 combines mirroring and striping functions on a minimum of four hard disks. Mirroring provides full redundancy and protects data in case of multiple drive failure (providing that data on one of each mirrored pair of drives is intact). RAID 0+1: Combination of striping and mirroring Characteristics: This configuration provides optimal speed and reliability.

  • Page 66: Raid 3

    ACS-9910 User’s Manual RAID 3 RAID 3 uses a mathematical expression that compares data from two drives and calculates a third piece of data called “parity”. Should one of the drives fail, parity data can be used to rebuild the failed data. Under RAID 3, parity data is stored on a dedicated parity disk. If two or more disks were to fail however, data would be lost.
