Proving The Results
EDITOR'S NOTE: CrystalDiskMark is not suggested for testing SSDs with versions prior to 3.0, as the software had not been written for or optimized to SSDs. therefore NAND wear conditions on segments tested may impact performance results.
That last section was a bit of a bomb, dropped dead-center on the belief system that many testers have had for years. So can I prove the results? Sure, of course we can. Let's go over the points we need to cover:
Alright, now that we're all on the same train of thought, it's time to leave the station. Using the free CrystalDiskMark software (version 2.2), we tested that same Mtron MOBI 3500 and analyzed our results after three test loops.
In the first set, the JMicron controller was used. The sequential read performance was 98.38 MBps, while write speed was 109.2 MBps. Dropping down to 512 KB chunks, the read speed is 96.31 MBps while write performance is 26.08. Finally, with the use of only 4 KB chunks, we see read performance at 23.17 MBps and write bandwidth at 0.326.
Now let's see how the Intel ICH10 controller reacts. The ICH10 controller yields a nearly identical 97.07 MBps sequential read performance, and slightly lower 105.1 write bandwidth. The results are slightly lower, but a 1.3% read performance reduction and 3.9% drop in write performance will probably not raise any concerns. Or are these results just the beginning?
Upon closer examination the 512 KB chunk tests perform essentially the same, and a 1.6% read speed decline is widened by the nearly 6% decline in write performance over the JMicron controller. This is beginning to get confusing again, and the 4 KB chunk test only makes matters worse. The Intel ICH10 actually records a 46.9% improvement over the JMicron JMB322 controller, recording 34.03 MBps over 23.17. The opposite is true of the ICH10 SATA controller when we look at 4 KB writes', which drop to 0.26 MBps for a 25.4% difference in favor of the JMicron.
So what does this all mean? How does this effect performance testing for reviewers, and results for consumers? Read on for my final conclusion on the topic.
