61RAID MODESA Redundant Array of Independent (or Inexpensive) Disks (RAID) is a systemthat utilizes multiple hard drives to share or replicate data among the disks. Thebenefit, depending on the selected RAID Mode (combinations of disks), is one ormore of increased data integrity, fault-tolerance, throughput or capacity whencompared to single drives.Deleting the current partition prior to changing RAID modes is highlyrecommended.Using identical hard drive(s) with the same capacity and RPM, and from thesame manufacturer are highly recommended for best capacity utilization.RAID 0 (STRIPING)RAID 0 (Striping) is a performance-oriented, non-redundant data mappingtechnique. It combines multiple hard drives into a single logical unit. Instead ofseeing several different hard drives, the operating system sees only one largedrive. Striping splits data evenly across two or more disks simultaneously,dramatically increasing performance.Striping can be implemented in disks of differing sizes, but the storage spaceadded to the array by each disk is limited to the size of the smallest disk.Although Striping is an easily implemented, simple configuration, Striping shouldnever be used for mission critical applications. The speed of operation isexcellent in comparison to other RAID modes.RAID 0Disk 1 Disk 2 Disk 3 Disk 4A1B1C1D1A2B2C2D2A3B3C3D3A4B4C4D4When you choose to insert only two hard drives, there is not limitation onthe order of hard drive insertion or the slot number. Under Basic Setup Menu, ifinserted all four hard drives, all will be assigned as the same mode.In Striping mode, if one disk in the RAID System fails, all data in installeddisks will be lost. |
