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.
When we look at each set of results, you can see we reached peak read and write speeds of 3087MB/s and 2931MB/s, respectively, over USB4 via Thunderbolt 4. Neither of these numbers were close to the advertised maximum speeds of 3800MB/s and 3200MB/s. Even so, this was still the fastest drive amongst all of the tests compared to everything else, which should be no surprise. You can again see how the write caching really changed the write capabilities of the SE920 for both sequential and random tests. In our USB 3.2 Gen 2x2 results, you can also see the SE920 1TB was competitive, but not necessarily the best. The SE920 produced the best sequential write numbers as well as decent read results. However, in our random 4K tests, other drives like the Crucial X8 2TB provided better numbers. Otherwise, the rest of the results can be interpreted from the graphs above.
