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 P400e continues is consistently exceeding the maximum rated speeds for writes and reads alike and here again we see the 4k writes scraping the bottom. This isn’t something we saw with other Marvell 9174 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: The P400e hangs near the bottom in overall score but certainly not a poor showing by any means. Each individual score is in the ballpark of the other drives as well.
