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. 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.
Netac claims the ZX20L 512GB's maximum read is pinned at 2000MB/s. Starting with the Seq1M Q8T1 test, the tested performance validated the specifications claims, and despite being slightly slower than other USB 3.2 Gen 2x2 drives, it remained generally consistent. The same can be said in the Seq1M Q1T1 section. The random read and write results were a similar pattern. In the RND4K Q32T1 tests, it was in the same ballpark as other portable SSDs in the same speed class. However, in the RND4K Q1T1 tests, it was simply no match for pretty much everything other than the discontinued Crucial X6 2TB and the also slow ZX10 2TB in write. It did perform as expected in read. I will let you make your own comparisons in our array of external USB SSDs in the graphs above.
