The Vertex 4 series from OCZ will end up being an intermediary controller between the old Marvell 9145 based Indilinx design which OCZ now owns and a new controller that is being designed in house by OCZ and the Indilinx team which came as part of the acquisition.  That doesn't mean this drive should be avoided, the prices are quite good with the 512GB model being one of the most affordable new drives on the market. [H]ard|OCP's testing had it performing at the top of the pack in many benchmarks and the drive comes with a 5 year warranty so you are getting quite a lot for a relatively low price.

"The Vertex 4 is a departure from OCZ's tried and true model of using third party controllers and firmware for its SSDs. Taking control of the firmware with the Vertex 4 gives OCZ the ability to tune the SSDs for speed and performance at lower queue depths and optimize for low latency. We test to see if the Everest 2 Platform delivers."
