The 840 Pro is stunning. Samsung have created a completely in-house package including both the controller and their own new 21nm toggle mode NAND. On release (Oct '12) this was the fastest performing deep queue depth consumer grade SSD available. Fast forward six months (Apr '13) and the 840 Pro still holds both the random read/write deep queue depth speed records of 384 MB/s and 326 MB/s, impressive considering how fast the SSD space tends to move. There are no obvious weaknesses, in-fact the 840 pro takes first place in nearly all of the speed categories and is only seriously rivalled by one drive, the OCZ Vector. To conclude, in terms of both outright performance, particularly server orientated, and value for money the 256GB and 128GB 840 Pros are amongst the top handful of drives currently available. ^{[Jun '13 SSDrivePro]}

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. ^{[Aug '14 SSDrivePro]}
