The Adaptec card I found would cost $250, which is about $200 more than I can spend on it.

I'll still make sure that I can return it if it fails. /Basic - To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
