OCZ Vertex 2 120GB SSD Review



To test the OCZ Vertex 2 drive, I installed a fresh copy of Windows 7 Professional on it and installed all of the drivers and Windows updates available. I did the same for each comparison drive so that they were exactly the same. All tests were run with the additional hardware at the same speeds, timings, latencies and voltages. This will keep any outside variables from interfering with the score and throwing out the tests. To get an idea of how the new SandForce controller compares, the Vertex 2 will be put up against two other SSDs and a traditional mechanical hard drive. The two comparison SSDs both use the Indilix Barefoot controller and are 64GB and 128GB in capacity to show both the capacities above and below the 120GB for the Vertex 2. One item of note, is that we chose to run the drives as the main drive for the system and not as a slave. The purpose of an SSD is to increase performance for your system, so it will in most situations, be run as a system drive and not as a slave drive, because of the limit in capacity. For this reason we did not run the tests as a slave drive, because we wanted you, our readers, to see how it performs as it should - as the main system drive with an OS and data on it.


Testing Setup:


Comparison Modules:



  • Drive Tests:
  1. HD Tune 3.50 Pro
  2. HD Tach
  3. SiSoft Sandra 2009
  4. Crystal Disk Mark
  5. ATTO Disk Benchmark
  6. AS SSD
  7. I/O Meter
  8. PCMark Vantage
  9. Windows Startup / Shutdown


The benchmarks will give a broad picture as to how each of the drives performs, so you can make your conclusions based on the performance of each drive. Most benchmarks are not yet optimized for solid state drives, but included in the benchmark suite is a new benchmark designed for testing SSDs - AS SSD.
