Stripped mirroring RAID architecture

Hai Jin, Kai Hwang
2000 Journal of systems architecture  
The disadvantage of RAID-1 lies in excessive redundancy, while the write performance of RAID-5 is only 1/4 of that of RAID-0.  ...  In this paper, we propose a high performance and highly reliable disk array architecture, called stripped mirroring disk array (SMDA). It is a new solution to the small-write problem for disk array.  ...  Modeling and performance evaluation In this section we present a utilization-based analytical model to compare the I/O access performance of RAID-0, RAID-1, RAID-5, RAID-10 and SMDA.  ...
