Don't buy this card. Or anything from LSI.This card would fail (the driver would crash) if you do anything involving high disk throughput. Copy a 40 mb file from another machine across the LAN? The computer this card is installed in would bluescreen.LSI customer support sent me a couple of BIOS updates and drivers that basically rendered my computer completely unable to boot. One of the largest wastes of money I've had in a while, especially considering the multiple evenings I've spent trying to fix this thing.Buyer beware.
