CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.
Benchmark Results: Again, the Marvell based Performance Pro drive compares favorably against the Force GT drives with the 180GB drive really falling behind due to its architecture and less dense NAND.
We are continuing to use the new PCMark 7 software since they have updated it to version 7 which is specifcially designed for Windows 7. It measures the performance of the latest PC hardware across a variety of common scenarios. PCMark Vantage 7 supports both system level and component level benchmarking and comprises several different test suites but for the purposes of this review, we employed the secondary storage suite. The nice thing about it is that you can submit your scores online and compare against others.
Benchmark Results: Not much variance between the three on this benchmark which some people feel offers some of the best insight to real world performance out of the synthetic benchmark.
Let’s see how they really fare in real world activities…
