As you will have gathered from the last page, we measured the performance Smart Response Technology using three different programs: CrystalDiskMark, PCMark Vantage, and PCMark 7. We will be looking at the test results from each program in the order they appear in the list above.
It’s important to note that we connected all the drives to SATA-600 ports on our motherboard rather than SATA-300 ports which could cause performance limitations.
We’ve included results for the Kingston SSDNow V+100 SSD for all the benchmarks we ran to give you an idea of how SRT compares to having an SSD as a main drive.
We used CrystalDiskMark’s default configuration for our tests, which benchmarked each SSD using a file size of 1000 MB with five test runs. Please read on to see the results.
In the sequential read test, enabling Smart Response Technology in maximized mode yielded an impressive 38.1% performance gain over the hard drive on its own. In Enhanced mode, there was an even greater 59.5% performance gain over the hard drive alone. In both sequential write tests, there was a 7.4% performance drop using SRT compared to the hard drive alone in maximized mode and a 10% drop in performance.
This could be for a number of reasons. The results displayed were recorded on the third run of the test to give the system a chance to “learn” our behavior. After even more repeats of the benchmark, the performance should be better, as the system will cache more of the data. But the Intel 311 Series SSD has a maximum write speed of 105 MB/s, which is probably the limiting factor in this case. As the hard drive has a higher maximum write speed, the caching of data actually has a negative impact on performance in this test.
In the random read test using 512 KB blocks, there was a much bigger difference in performance than in the sequential test. In maximized mode, there was a massive 249% improvement in performance, and in enhanced mode there was an even greater 272% improvement. In the random write test using 512 KB blocks, there wasn’t any improvement in performance with SRT enabled in enhanced mode. But in maximized mode, there was an 84% improvement in performance.
With SRT enabled in maximized mode, there was a massive 4434% improvement in performance over the hard drive alone in the random read test and a 3714% improvement in the write test using 4 KB blocks. In maximized, mode, SRT also outperformed the Kingston V+100 128 GB SSD by 13% in the read test and by 50% in the write test using 4 KB blocks.
When SRT was enabled in enhanced mode, however, there was no improvement over the standard hard drive in the write test using 4 KB blocks. There was still an impressive 4586% improvement in performance in the read test using 4 KB blocks, though.
