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 ZX10 2TB's maximum read and maximum write are pinned at 1050MB/s. Starting with the Seq1M Q8T1 test, the tested performance validated the specifications claims, and actually came out slightly ahead of other USB 3.2 Gen 2 drives too. Unfortunately, the same cannot be said in the Seq1M Q1T1 section, where the ZX10 actually came in behind all other portable SSDs in its speed class. The random read and write results were a similar pattern. In the RND4K Q32T1 tests, it was in the same ballpark, if not edging out 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 in write, although it performed pretty well in read. I will let you make your own comparisons in our array of external USB SSDs in the graphs above.
