With the introduction of the Vertex 4, OCZ's SandForce period appears te come to a close. While the Vertex 3 and Agility 3 series won't be phased out right away, it is clear that the Vertex 4, Octane, and Petrol SSDs will receive all their attention from now on. This is not surprising considering Indilinx is part of OCZ. Who doesn't prefer selling their own product instead of someone else's?
It's striking how much faster the Vertex 4 is than the Octane, the SSD with a first-generation Everest controller. Whether the benefit comes primarily from hardware or software optimalisation we'll leave open for discussion. Either way, it's impressive to make such progress in a relatively short amount of time.
Unfortunately, the PCMark Vantage benchmark puts a bit of a blemish on the overall impression. In the majority of benchmarks the Vertex 4 is extremely fast, even setting a few new records. The AS SSD and Iometer benchmarks prove that the Vertex 4 is a speed devil, especially when writing. In PCMark7, the benchmark closest to real-life, the Vertex 4 is not quite as impressive and more in line with other modern Serial ATA 600 SSDs. This is not a new phenomenon. There is very little difference between most modern SSDs during normal daily use.
All in all we are very enthusiastic about the Vertex 4. Granted, the Everest controller has not had the time to prove its reliability yet. OCZ is aware that it cannot afford to repeat Vertex 3-like problems, and has said that the new Vertex 4 has been tested en validated extensively. The fact they are willing to include a five year warranty indicates that they fully believe in their product. At the moment, we are prepared to believe them as well. There is no reason not to.
