I have read multiple blog post that people recommend to disable NCQ/TCQ features of individual drives that is in the RAID group [1] in a hope to improve RAID speed. I guess there should be some observation in the field that results such a conclusion. However, this idea does not make sense in theory. While drives can handle multiple outstanding scsi commands at the same time, why don't we take advantage of this to increase the disk access throughput ?
