According to your IOMeter results (http://www.storagereview.com/articles/200601/250_iometer.png) and results from other sites, SIL controller dont make command reordering. When queue depth increase from 1 to 32 there is no any increase in perfomance for non NCQ HDDs. So non NCQ HDDs results are incorrect in IOMeter and partly for others tests.
According to this (http://www.behardware.com/art/imprimer/624/), most NCQ HDDs reorder command not better than controller. In other words, they have "fake" NCQ.
