Compressible Data Test
As you will have gathered from the previous page, we measured the performance of each drive using two different programs: CrystalDiskMark and AS SSD. We will be looking at the test results from each program int he order they appear in the list above.
It is important to note that we connected the SSDs to a SATA-600 port on our motherboard rather than a SATA-300 port, which could cause performance limitations.
We set CrystalDiskMark to “All 0x00 Fill mode” to evaluate the performance of the SSD when dealing with compressible data.
On both the sequential read and write tests, the two drives exhibited a similar level of performance.
As you can see, the two drives once again exhibited a similar level of performance in both the random read and random write tests using 512 KB blocks.
On the random read test using 4 KB blocks, the Zalman F-Series exhibited 6% better performance than the Kingston SSDNow V+200. However, on the random write test using 4 KB blocks, the two drives exhibited a similar level of performance.
