EDITOR'S NOTE: According to FutureMark's PCMark Vantage White Paper document regarding HDD tests (see page 27), the workload for each subsystem depends heavily on the overall system configuration. Different components can be severe bottlenecks and cause variance in the results of the actual component performance measurement. Fragmented HDDs, old drivers, cluttered OS, 3rd party applications etc. are all factors which will affect the benchmark results. The PCMark HDD test consists of benchmarks using software applications that depend on processor, memory, and graphics hardware. Additionally, NAND wear condition may impact performance results.
PCMark05 (and PCMark Vantage for Windows Vista) are tools intended to test real-world performance for computer hardware. With specific regard to SSD products, Benchmark Reviews configures PCMark to only conduct 'HDD' tests. With a focus on storage media, PCMark05 tests in five different areas and then generates a composite PCMark score.
In the example below, the average of three tests on the G.Skill FM-25S2S-64GB SSD were charted and compared. During our testing the first test was discarded, as were the highest and lowest test. This essentially leaves the most average representation of performance.
The JMicron SATA controller appeared to run very consistent tests from start to finish, but there were rare occasions where the highest or lowest test was more than 10% out of normal range. To the same extent, and possible more frequent, was the occasional irregularity in a test performed on the Intel ICH10 controller. Despite these test irregularities (which were discarded as noted above), the averages indicated a performance benefit for the Intel ICH10 SATA controller over the JMicron JMB322.
While I would normally not consider the 3.5-6.4% margin to be anything worth mentioning, the 25.1% improvement in Virus Scan results was enough to make me take notice of Intel's ICH10 controller. Additionally, the File Write test showed a 13.2% improvement for the ICH10, even though all of our previous tests with other software have claimed differently.
This is all good for broadening the differences between Intel and JMicron SATA controllers, even though the results are extremely confusing between software tools. But the real interesting news is how PCMark05 compares the performance of one drive to another.
So if we take PCMark05 at face value, the Mtron MOBI 3000 seems to easily out-perform the G.Skill SSD, and doubles the performance of the best Hard Disk Drive products. Sound believable? Not to me, it doesn't.
Since I personally use all of these products each and every day on several different test systems, I can assure you that PCMark05 is not properly comparing HDD products to SSD counterparts. I suppose the disclaimer must rear its ugly head again, since Futuremark was really quite specific in naming this test 'HDD' and not storage media. Which brings me to my final thoughts and conclusion...
