The OCZ Vertex 3 SSD is based on the second-generation SandForce's SF-2281 SATA 6Gb/s controller and maintains all of the original core technology introduced in the original SF-1200 series, but now improves SSD performance with 20% faster IOPS and 40% faster sequential read/write throughput. OCZ promises 60,000 IOPS at up to 550 MB/s transfer speeds with the Vertex 3 SSD, and Benchmark Reviews confirms that they're keeping this promise with tests of the new storage device on a B3-stepping Sandy Bridge platform against the Crucial RealSSD C400.
