I'm curious what > your use-case for realtime is? In my setup I need mostly sequential read/write access to a number of huge files (>1GB) as well as small ones. My 16-disk system, providing 1GB/s of sequential access data rate, chokes when file fragments are smaller than ~32MB. Using 32MB extents of the regular data section helps, but fragmentation still develops. I hope (maybe I am wrong) that the realtime section with its fixed extents eliminates the fragmentation issue.
