Steve,

Have you compared the results by subscore, where does the Areca make a difference?

BTW, 4KB iometer random read is not much to go by to determine the best storage system
8KB (workstation pattern) and 16/64KB is just as important, maybe more so than 4KB, although, if 4KB is good then the rest should be good as well.
Write Through is probably the culprit to the 9211s overall score.
