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 Ramesh
