Average Bench: 90.5% (268th of 1018)

Based on 7,178 user benchmarks.  Models: OCZ-VERTEX4, OCZ-VERT OCZ-VERTEX4, OCZ-VERT EX4

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 OCZ Vertex 4 comes with a 5 year warranty, OCZ are trying to make up for poor quality control on previous models... Time will tell, but on the face of it this is the best performing (benchmark wise) SSD you can buy today.
