In fact I have to assume PCI-E 1.0 since it doesn't specify (not that it's an issue, 8 lane 1x vs 4 lane 2x is more or less the same thing; though 4x is more future proof since there is likely to be a slot that big on future motherboards at /least/ for physics GPU support). Are you suggesting the LSI based Intel card because you know it to properly support >32 bit LBA? -- 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
