The AMD Radeon R7 SSD is manufactured by OCZ (Toshiba). The release of the R7 is in line with OCZ's approximate six-monthly release cycle. Apart from newer NAND memory, the R7 has the same components as the OCZ Vector 150. Comparing the AMD R7 and Vector 150 shows that peak performance is broadly unchanged. We don't have any user samples for the new R7 yet but based on components, it's reasonable to assume that real-world effective speeds will also be comparable to the Vector 150. Although the 240GB R7 SSD is a strong performer, disappointingly, it brings nothing new to the table in terms of hardware. Unless OCZ/Toshiba can pull something out of the bag they will continue to loose market share to Samsung who are still managing to innovate with each of their releases; most recently the 850 pro series.

The 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer.
