NVRAID 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 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1. 
Spanning (JBOD): JBOD provides a method for combining drives of different sizes in to 
one large disk. 
RAID 5: RAID 5 provides fault tolerance and better utilization of disk capacity.

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 1, 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.
