I selected that model in part because it at least claimed to support NCQ. I'm not sure if it reflects NCQ or not, but I do have /sys/block/sd[abc]/device/queue_{depth,type} which show simple and 31 respectively. Samsung's page for the drive also says it supports NCQ: http://www.samsung.com/Products/HardDiskDrive/SpinPointPSeries/HardDiskDrive_SpinPointPSeries_SP2504C.htm -- -Cheetah "Reality is that which, when you stop believing in it, doesn't go away". -- Philip K.
