Crystal Disk Mark 3.0 is in the spotlight. Just a bit of background information; higher capacity drives tend to perform a little better in these tests. Drives like the OCZ Vertex 450 has a big advantage, because it does not compress data on the fly, In this particular benchmark, the ability of a controller and flash memory to deliver high IOPS will provide huge benefits to the score as well. As you can see in our graphs above, the OCZ Vertex 450 256GB performed very well, as expected. OCZ rates the Vertex 450 to be capable of delivering 90,000 IOPS, whereas the Vector is rated at 100,000 IOPS. As such, the Vertex 450 is generally a little bit below the Vector in all but one test. This means, like its bigger brother, this SSD delivered close to -- if not class leading -- performance in every Crystal Disk Mark 3.0 test.
