Benchmark: PCMark Vantage
That's unexpected. Having scored so well in each previous benchmark, both Vertex 4 drives struggle to get going in PCMark Vantage's simulated real-world tests. In this benchmark, the 256GB and 512GB Indilinx Everest 2 drives are considerably slower than the available competition.
The benchmark is admittedly dated, but it has proven to be a good indication of real-world performance during light, everyday tasks, and the Vertex 4 results aren't anywhere near the expected level.
OCZ's explanation for these results is that "PC Mark is mostly based on compressed files performance which means it's not a good representation of the capabilities of the Vertex 4."
"PC Mark also intentionally keeps a low queue depth in order to simulate real world performance. However PC Mark also specifically runs unaligned I/O which is not simulating user experience as a majority of the I/O in Windows 7 is aligned."
