The OCZ Vertex 4 512 GB is a heavy duty product, a suitable choice for desktops, work stations, servers, and high-performance notebooks. Introduced by OCZ Technology, the OCZ Vertex 4 differs from most performance SSD products on the market in that it has an Indilinx controller chip, not the more commonly used SandForce controller. Indilinx, a South Korean company, was acquired by OCZ Technology, and both teams collaborated on the new controller chip used in the Vertex 4.
