Notebookcheck says:

... While the PM961 didn't quite hit the targeted read rates specified by the manufacturer, it still outperformed not only the predecessor PM951, but also the SM951(a) and 950 Pro, which are actually higher up in the lineup - Lenovo ThinkPad T460s Long-Term Review Part 2 | June 2016
