About Crystal Disk Mark

- Measure Sequential and Random Performance (Read/Write/Mix)
- 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 Crucial P5 Plus 1TB is rated at up to 630,000 IOPS read and 700,000 IOPS write, which is good. 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. Crucial claims the P5 Plus 1TB's maximum read and maximum write are pinned at 6600MB/s and 5000MB/s, respectively. Looking at the read and write results of all four sections, the P5 Plus 1TB was a bit behind in the linear read and write section against other PCIe 4.0 NVMe drives, but the numbers were expected given this is a budget drive. It performed admirably, even coming in first place, in the Seq1M Q1T1 read test, but the write results were behind both the XPG Gammix S70 Blade and WD_BLACK SN850. A similar story can be told in the RND4K Q32T1 tests, even getting beat by PCIe 3.0-based drives in read, but nonetheless remained mostly consistent with the rest of the group. Lastly, in the RND4K Q1T1 segment, the P5 Plus was behind everyone in the write test, but its read results were very good. I will let you make your own comparisons in our list of SSDs in the graphs above.
