Something new we are starting to do is run the storage consistency test in the PCMark 8 application from Futuremark. In short, it looks at drive performance degradation as the drive becomes “dirty” and how it rebounds after given time to recover and run background routines like garbage collection and TRIM. This takes nearly a day to run through all of the iterations of test sets. Since most of our benchmarks show the drive performance in a clean state, this is a nice contrast to provide yet another view of performance. PCMark 8’s storage benchmark test contains workload traces from Adobe Photoshop, Adobe Illustrator, Adobe InDesign, Adobe After Effects, Microsoft Word, Microsoft Excel, Microsoft Power Point, World of Warcraft and Battlefield 3.
The PCMark 8 Consistency test has five phases:
Steady state phase
Benchmark Results: We decided to grab a random drive from our pile so we had at least one other in the chart for comparison and it happened to be the OCZ Vector 460 240GB. It’s easy to see a pretty large gap in performance between the two on this test even though on most of the other benchmarks, they were relatively close in performance. To be fair, the MX100 is a budget friendly drive and the Vector is OCZ’s flagship drive costing much more and specifically designed to maintain performance after heavy use (hence their marketing quip “Not afraid to play dirty”). As we get a chance to test more drives on this benchmark, we’ll have a better idea where the mean performance falls.
