Samsung [(evo950 nvme) vs (pm951 nvme)] vs. Toshiba [OCZ RD400 1Tb nvme] M.2

See attached ezfio data spreadsheets for comparison running in ThinkPad P70 Mobile Workstation. For my money the PM951 performs much better in key testing regimes overall at about half the cost of EVO 950.

Update: September 25, 2016.

The Toshiba OCZ RD400 Series Solid State Drive, PCIe NVMe M.2 1TB with MLC Flash (RVD400-M22280-1TB) is a very high-performer on the Lenovo P70 mobile workstation and takes first place I'd say at this point.
