Characteristics RAID controller breaks the data into blocks and distributes the pieces to both drives. RAID controller writes the same data to both drives.RAID 0 drives can be mirrored using RAID 1 techniques, resulting in a RAID 0+1 solution for improved performance plus resiliency The controller combines the performance of data striping (RAID 0) and the fault tolerance of disk mirroring (RAID 1). Data is striped across multiple drives and duplicated on another set of drives.
Customer Benefit RAID 0 (Striping) offers performance benefits over a single hard drive configuration. This bundle is ideal for early adopters and power users that manipulate large files. RAID 1 (Data Mirror) offers the customer data integrity by having the same data on two drives. If one drive fails, the customer's data is still intact on the other hard drive. This bundle is ideal for applications where data integrity is of utmost importance. This is not data backup.RAID 0+1 offers the customer the performance gained from RAID 0, the same time provide same overhead for fault tolerance as mirroring alone. It has high input output rates due to multiple stripe segments. This is ideal for applications that need high performance and system reliabilty.
