Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, power on information as well as the characteristics of the SSD. We can see that our counterfeit KingFast F3 Plus SSD is capable of TRIM as it is not greyed out, much like AAM.
Our Crystal Disk Info testing is done before any other metrics and right after SSD installation. In the case of the fake KingFast F3 Plus SSD, there was already 5GB total host reads and writes. This may be the case with some manufacturers as each and every SSD is tested before final packaging. In examining the result of the authentic F3 Plus CDI result (below), we the same did not appear to be the case. Similarly, a concern may be evident in SMART IDs 01, C3, c9 and CC where read errors seem to have occurred.
Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or random data which is, for the most part, incompressible. In the case of our counterfeit KingFast F3 Plus SSD, we are providing the highly compressible data result on the left and the incompressible data result on the right.
A point we want to demonstrate with respect to identification is that our fake SSD did fine in testing with highly compressible data, or rather, data that we might typically see in operating system and software use. In fact, we could not visibly tell the difference between the counterfeit SSD and the real one in normal every day use. In the case of this SSD anyway, the single biggest flag were the incompressible data performance results.
