Surveillance Test Tool
WD provided a test tool for measuring Command Competition Time (CCT) when we tested the WD Purple. The tool shows the percent of commands completed in millisecond blocks of time. Ideally, you want all of your commands to complete in the least amount of time. Although we're showing both read and write tests on the chart, surveillance systems spend over 90 percent of the time writing data and less than 10 percent reading it back.
In the first test of eight channels at 720p, the Seagate Surveillance was able to complete 83 percent of the workload in under 5ms, higher than the 66 percent of the Purple.
Moving on to 16 channels, still at 720p, the Surveillance falls off slightly, allowing the WD Purple to complete 59 percent under 5ms, while the Seagate only completed 1.7 percent.
With 32 channels and 720p, both drives are pretty even.
32 channels and 1080p show similar results to what we found with 720p.
