IOPS Scaling
In these tests, we tested the drive's ability to tackle multiple input/output operations. Again, we compared the 256 GB OCZ Vector solid state drive to the industry standards - the Intel 520 Series SSD and the Intel X25-M G2. If you wish to see how the OCZ Vector compares to other solid state drives, take a look at our Solid State Drive Performance Comparison Guide, which we will be updating shortly.
Even though the Indilinx Barefoot 3 controller does not compress data for better performance, we continue to test the drive using compressible and non-compressible data to mimic real-world usage. So the following results are based on the average of separate tests using compressible and non-compressible data.
