IOPS Scaling
In these tests, we tested the drive's ability to tackle multiple input/output operations. Again, we compared the OCZ Vertex 2 to the OCZ Agility 2 (E). If you wish to see how the OCZ Vertex 2 compares to other solid state drives, take a look at our Solid State Drive Performance Comparison Guide.
Do note that these results are based on the average of separate tests using compressible and non-compressible data. This is to address the fact the newer SSD controllers like the SandForce SF-1222 compress data for better performance and lower wear on the memory cells.
