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 we see similar scores that show the 840 Series having very consistent performance which is something of a trend with the Samsung drives.
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: Honestly, I didn’t think the 840 Series drive would score as high as it did in this benchmark given the write performance as compared to some of the other drives which illustrates that this benchmark is much more read than write oriented.
