If you don't mind, could you share with me the standalone card that you 
use?

I used SYBA SI-PEX40064 
(http://www.newegg.com/Product/Product.aspx?Item=N82E16816124064)
and under load (mkfs.ext4 -c -c on just one drive) it drops the drives 
and a reboot
is required to get them back. This means I cannot put raid component on this
without risking degrading the array. I believe SYBA based on Marvell 
88SE9215.

BTW, have you stressed your card through a rebuild/checkarray?

Thanks
