The Vertex 4 is just over a year old but thanks to its recent firmware update (1.5), it still manages to perform almost on a par with the best drives currently available. One of the striking aspects of the Vertex is its well-rounded performance profile. With an AS-SSD score of 1137 and a real world speed of 548 the Vertex 4 is able to cope extremely well with both server and consumer type workloads. This drive uses the new Indilux Everest 2 controller, which unlike the previous generations of this drive which used a SandForce controller, is able to cope admirably with both compressible and incompressible data. Overall, the Vertex 4 is a great performing SSD that said, there are better value for money (and younger) drives available, including the Vertex 4's own successor, the OCZ Vector[Jun '13 SSDrivePro]

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]
