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: The incompressible nature of the benchmark is evident on the SandForce drives and the reduction in performance on the TeraDrive CT3 is pretty dramatic. Sequential scores are at least half of what the larger drives are and is typical of what we see with the smaller drives.
This is our first use of the new PCMark 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: The PCMark 7 scores overall show lesser performance than the other SandForce drives but to be fair the smaller drives always perform slower than their larger counterparts as we have mentioned.
