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 525.3MB/s reads and 301.7 MB/s writes. 512K test results reached 384.6MB/s read and 304.2 MB/s write performance. 4K tests produced 29.59MB/s read and 87.87MB/s write performance. While the sequential read speeds were again very good, the 4K random transfer speeds with 32 commands queued up were mid-pack.
256GB Premier SP610 SSD CrystalDiskMarkResults
The chart below summarizes 4K random transfer speeds with a command queue depth of 32. While the ADATA Premier SP610 falls mid-pack in this chart, bear in mind that many of the drives below it are much older, previous-generation SSDs, so it’s really close to the bottom of the pack when considered against the currently-available competition. That said, most consumers are never going to have a situation where they’ve 32 outstanding I/O commands, so this test, while interesting from a performance perspective, isn’t that relevant for users that aren’t running servers.
In the next section, we continue our testing using Iometer to measure input/output performance…
