About Crystal Disk Mark
- Measure Sequential and Random Performance (Read/Write/Mix)
- Peak/Real World Performance Profile
From: Developer's Page
Moving on, Crystal Disk Mark 8.0 is our next benchmark. For a bit of background information, higher capacity drives tend to perform a little better in these tests. The ability of a controller and flash memory to deliver high IOPS will provide huge benefits to the score as well.
Lexar has made maximum claims of 6000MB/s write and 7000MB/s read for the NQ780 4TB. We normally see these peaks through Crystal Disk Mark, and from our results, you can see our unit surpasses these numbers. In the sequential 8-queue results, the Lexar NQ780 4TB peaked at 6524.77MB/s write and 7431.88MB/s read. This was the fastest in reading and second fastest in writing across the four drives compared. The sequential single queue results were more mixed, with the slowest read speed but fastest write result. In the random 4K, 32-queue test, its read and write performance was the second fastest. Finally, in the random 4K single queue test, the NQ780 4TB provided the slowest read and second slowest write. Overall, it does show some capable sequential capabilities, but less impressive random performance. You can make other comparisons from the graphs above.
