N2 - In this paper, a simple codec algorithm based on Reed-Solomon (RS) codes is proposed for erasure correcting in RAID level 6 systems. Unlike conventional RS codes, here this scheme with a mathematical reduction method, called Reduced Static-Checksum Table Approach, could improve coding performance. We used Reed Solomon codes which are designed according to characteristics of advanced RAID systems to handle two disk failures in RAID system. Also, this scheme performs all computations with only simple exclusive-OR (XOR) operators just the same as Even-Odd codes. This new XOR-based RS codes could adapt to implementation in terms of improving reliability and flexibility.
