OCZ has confirmed the existence of a new solid state drive, believed to be the Vertex 5. Current estimates place the launch as occurring sometime next month, though OCZ would not confirm naming or launch window. They did say that it features an updated Barefoot 3 controller and 20-nanometer NAND flash.
The Vector SSD is currently OCZ's fastest SSD and is based off of the Barefoot 3 platform. It's possible that the next solid state drive could be called something like Vector 2, but Vertex 5 makes more sense. Earlier this year, OCZ updated the Vertex 3 to use 20nm NAND flash and called it the Vertex 3.2. All other features remained the same.
Last year, OCZ had some financial troubles that resulted in mass layoffs and discontinuation of numerous product lines.
