PCMark Vantage comes as close as we get to approximating real-world performance using a synthetic benchmark. The Application Loading metric measures disk drive performance while loading Microsoft Word 2007, Adobe Photoshop CS2, Internet Explorer 7, and Outlook 2007.
This is just the beginning of the trend, but notice that both disk drives fall to the back of the line. Even Western Digital's VelociRaptor can't keep pace.
While PCMark Vantage is the closest thing to showing real-world performance, it has its own flaws. When we were testing the Vertex 3 Pro, we discovered about a 5000 point variance in the final score (50 000-55 000 PCMarks). When we examined the scores of the individual tests, we noticed that the drive would either perform outstanding in Windows Defender or Application Loading, but never both. We have seen variances with PCMark in the past and this is well within those tolerances, but it is something we wanted to mention for those curious about our numbers.
Using >99% streaming reads, Vertex 3 Pro shows its dominance in the gaming throughput test, though it doesn't come anywhere near its rated specifications.
The video editing test is split more evenly between reads and writes. This time all three SandForce drives top the chart, though the Vertex 3 Pro still leads by a healthy margin.
A Windows Defender scan in Windows Vista shows a small improvement for the Vertex 3 Pro.
The Windows Media Center test runs SD video playback, SD video streaming to an extender, and records an SD video concurrently, yielding an even split between reads and writes. Here, we see OCZ's Vertex 3 Pro exceed the cap that would have been imposed by 3 Gb/s SATA, trouncing the other drives in this test.
Hot off of that victory, we're faced with a situation where the Vertex 3's read performance should allow it to shine in this predominantly read-based test. Instead, the X25-M leads the pack this time. We can only assume that the data involved in this metric is not handled well by specific versions of SandForce’s firmware.
The photo import test is also mostly read-based, so it isn't a surprise to see the newest SandForce drive lead the pack again considering how well it performed in CrystalMark.
OCZ tops the chart again. Remember that this is naturally almost all read-based.
