CrystalDiskMark 3.0 Tests

CrystalDiskMark 3.0 is a file transfer and operational bandwidth benchmark tool from Crystal Dew World that offers performance transfer speed results using sequential, 512KB random, and 4KB random samples. For our test results chart below, the 4KB 32-Queue Depth read and write performance was measured using a 1000MB space. CrystalDiskMark requires that an active partition be set on the drive being tested, and all drives are formatted with NTFS on the Intel P67 chipset configured to use AHCI-mode. Benchmark Reviews uses CrystalDiskMark to illustrate operational IOPS performance with multiple threads. In addition to our other tests, this benchmark allows us to determine operational bandwidth under heavy load.

CrystalDiskMark uses compressed data, so sequential file transfer speeds are reported lower than with other tools using uncompressed data. For this reason, we will concentrate on the operational IOPS performance in this section.

CrystalDiskMark 3.0 reports sequential speeds reaching 507.7 MB/s reads and 492.5 MB/s writes. 512K test results reached 404.3 MB/s read and 470.2 MB/s write performance. 4K tests produced 24.50 read and 86.16 write performance. All CrystalDiskMark results produced by this 240GB OCZ Vector 150 SSD were roughly equal to the Vertex 450 series, but were not high enough to surpass OCZ’s Vector solid state drive.

Maximum 4KB IOPS performance results at queue depth 32 are reported in the chart below. These values represent the performance levels for several enthusiast-level storage solutions, and illustrates which products offer the best operational performance under load:

In the next section, we continue our testing using Iometer to measure input/output performance…

    Nice review as always Olin.
    Just one thing…
    How does it compare to a samsung SSD?
    Or did I miss that part?

    1. Olin Coles

      Unfortunately we do not have a Samsung SSD to compare against because our requests have not been answered. However, for comparison purposes, the Samsung 840 Pro uses 21nm NAND whereas Vector 150 uses 19nm NAND flash. Vector 150 reads at 550 MB/s and writes at 530 while Samsung 840 Pro reads at 540 and writes at 520 MB/s. Both read at 100K IOPS and offer a five-year warranty, but Vector 150 features 50 GB/day endurance compared to 40 GB/day for Samsung 840 Pro. I hope this helps!

    Thank you.

    I guess Samsung don’t need the reviews at this point in time.

    These are awfully close spec wise. Now to wait it out for reliability info.
