Samsung 830 Series 256 GB SSD Review
Compressible Data Test
Contents
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 in the 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.
As you can see, the Samsung 830 Series outperformed the Crucial M4 in the sequential read test by a considerable margin of 19 percent. The 830 Series achieved even better performance in the sequential write test, beating the Crucial M4 by 87 percent.
Once again, the Samsung 830 Series performed better in the random read test using 512 KB blocks, beating the Crucial M4 by a margin of seven percent. In the random write test using 512 KB blocks, the two drives exhibited a similar level of performance.
The Samsung 830 Series achieved the highest score in the random read test using 4 KB blocks, outperforming the Crucial M4 by six percent. The 830 Series also came out on top in the random write test using 4 KB blocks, achieving seven percent better performance than the Crucial M4.
