Building on the authors' prior paper in, they present an improved model for large partial stripe following full stripe writes in RAID 5. This was necessary because they observed that their previous model tended to underestimate measured results. To date, they have only validated these models against RAID systems with at most four disks. Here they validate their improved model, and also their existing models for other read and write configurations, against measurements taken from an eight disk RAID array.
