About a year or so ago, OCZ bought Indilinx planning to develop their own proprietary controller, and we've been waiting to see the results. First came the "Indilinx-Infused" Everest 1 controller on the OCZ Octane, and it was impressive but not entirely reality-altering. Maybe we're curmedgeons but we wanted more. And now OCZ has the Vertex 4, featuring the newest Everest 2 controller, promising enthusiast-classed performance to battle the SandForce drives.
