See, I was right about my post.
You guys should really make a official XS realworld HDD bench instructions on how to make this bat file, standardize the programs used in it, make some official "File folders" with lots of smaller files inside and a large .iso file for testing real world copy performance, that one could download of of rapidshare or something.
I have done this on my systems and use it for my own comparisons. But maybe something simmilar should be devised on XS level.

Napalm, at what point would you say it is beneficial to buy the Areca controller you have? Only if one plans 4xSSD+ in R0? Or would I see real world benefits for only 2?
What realworld differences in seconds can I expect vs. ICH10? In your well educated guess of course!
