PCMark 8's storage benchmark is once again based on traces, but this time around, modern software is used. PCMark 8 contains traces of Adobe Photoshop, Adobe Illustrator, Adobe Indesign, Adobe After Effects, Microsoft Word, Microsoft Excel, Microsoft PowerPoint, World of Warcraft, and Battlefield 3. The total score is determined by taking the geometric mean of the different subscores. Again, all traces are played back in "real time", which includes idle time. As a result, scores of different SSDs are very close to one another, just as was the case for PCMark 7. This is representative of the real world, as distinguishing modern SSDs from one another in regular consumer applications is close to impossible.
Recall that PCMark 7 also shows a Raw score for each test. Similarly, PCMark 8 shows the average playback speed of the traces' drive activity. These metrics therefore do not include idle time, and once again show the actual underlying performance differences of the SSDs.
The Iridium Pro is slightly faster than the Crucial MX300 with a storage bandwidth of 251 MB/s, but the 850 Evo remains the undisputed king in this practice test.
