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: Showing indifference to the type of data employed, the OCZ Vertex 4 drives scored very well on the writes where the SandForce drives just can’t keep pace although the Vertex 3 gives is it a good go. Again we see strong performance in the 4k writes and 4K reads weren’t bad either.
We are continuing to use the new PCMark 7 software since they have updated it to version 7 which is specifically 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: The SandForce based drives lead the way here with the Vertex 4’s and the Samsung neck and neck although this benchmark generally doesn’t show huge variances between drives unless one is particularly weak or strong.
