About Crystal Disk Mark

- Peak/Real World Performance Profile

From: Developer's Page

Crystal Disk Mark 8.0 is in the spotlight. Just 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. The XPG Gammix S70 Blade 1TB is rated at up to 740,000 IOPS read and write, which is very impressive. As manufacturer peak read and write performance ratings are usually achievable using Crystal Disk Mark, whether a drive lives up to its marketing claims or not can be validated by this program. XPG claims the Gammix S70 Blade 1TB's maximum read and maximum write are pinned at 7400MB/s and 5500MB/s, respectively. Looking at the read and write results of all four sections, the Gammix S70 Blade 1TB absolutely dominated the linear read and write section against other PCIe 4.0 NVMe drives and exceeded the advertised figures slightly. It performed admirably in the Seq1M Q1T1 write test, but the read results were behind both the Crucial P5 Plus and WD_BLACK SN850. Things continued to drop in the RND4K Q32T1 tests, even getting beat by PCIe 3.0-based drives, but nonetheless remained mostly consistent with the rest of the group. Lastly, in the RND4K Q1T1 segment, the Gammix S70 Blade remained behind the SN850. I will let you make your own comparisons in our list of SSDs in the graphs above.
