@mikep, please trim down your posts... there is a lot of whitespace/"bumpf" in your posting which could have been trimmed to make the post more readable and consise.

The hdparm tool can show the read performance speed but it varies depending on
the current system load.
A better way to test the performance will be to use the disk performance test
tool from the DSS V6 console which use "dd" command to gather the measurement
results to see how fast your RAID unit works. Don't do the write performance
tests as they are only possible on a RAID unit where no vg is created.
To access the disk performance tool from the DSS V6 console, press ctrl + alt +
W -> System benchmarks -> Disk performance test.

You can have a look at some of our KB articles about RAID performance tuning:

Thanks for your information.
Could you please give some suggestion about how to optimize the Areca ARC-1680 / ARC-1880 series RAID Card ?

Best Regards!
