We can basically write the same conclusion for the Plextor M5 Pro 256GB as we did for the 128GB model. It's the fastest SSD in its category, and set new records in AS SSD and PCMark Vantage, and came up 15 points short of the high score in PCMark 7. Very impressive figures indeed. The incredible performance, the good warranty conditions and outstanding track record of both Marvell and Plextor make this an excellent product.
