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. Although the OCZ Vertex 4 256GB did not post earth shattering results in the sequential and 512K read/write tests, the subsequent two is definitely something we had hoped for. Don't get me wrong, I am not saying the first two is bad -- the Vertex 4 still hold its own among the best SandForce drives. However, as you can see in our graphs above, it was particularly outstanding in our 4K write and 4K QD32 read tests; in fact, the Indilinx Everest 2 based drive absolutely shattered the competition. The high IOPS capability of OCZ's flagship paid off, and these are the stuff that will make a big difference in real life performance.
