Definition of RAID 5 Volume

We can define RAID 5 Volume as an acronym for Redundant Array of Inexpensive (or Independent) Disks. RAID 5 volume existing on three to 32 disks. RAID 5 volume can offer better performance for reading process. In Windows Server 2003 RAID 5 volume is not expandable or mirrored, and RAID 5 volume does not have concern with the boot and system partitions. RAID 5 volume is fault tolerance but the fault tolerance is provided by equality information. As with a striped volume, data is written regularly across all disks in 64-KB chunks. Unlike with disk striping, the available space (the stripe) on one disk is used for equality information. To enhance performance, the equality information is split across all the disks in the volume, written in stripes like the data. Writing performance is inferior, because the equality must be calculated during the writing process. If most processes are read-oriented, RAID 5 volume provides noteworthy performance advantages.

RAID 5 Volume

How many disks is part of the RAID array defined the utilization of disk. The equivalent of one disk is used for writing the equality information. If we have three disks, one-third of the total disk space is used for equality information, so we will be able to use two-thirds of the space we purchase for data. If we have 10 disks in the array, only one-tenth of the total space will be utilized for equality. However, when we use more disks we can get more excellent disk usage.
