The last time we tested the OCZ Vertex 4, it was powered by a dual-core Marvell controller that combined technology from separate sources. This time, the OCZ Vertex 450 solid state drive is made of in-house components. Featuring an Indilinx BF3-M10 Barefoot 3 controller that supports 20nm Synchronous Multi-Level Cell (MLC) NAND flash components with AES-256 encryption and Trim support, Vertex 450 is good for 540 MB/s read speeds over a SATA 6-Gb/s connection. In this article Benchmark Reviews tests the 240GB OCZ Vertex 450 SSD, model VTX450-25SAT3-256G, against the leading competition.
