This is my NAS storage server based on Debian Linux. It uses software RAID and 20 one terrabyte hard drives. It provides a total usable storage capacity of 18 terrabytes in a single RAID 6 array.
One of the remarkable side effects of using 20 drives within a single array is the read performance of over one gigabyte per second.
