They are very slow in some tasks
Samsung 1080 Pro SSDs have appeared on the market, which the company itself did not present. And all because these are fakes.
The authors of Quasarzone discovered such SSDs in the vastness of Chinese stores, including Aliexpress. According to the stated parameters, the SSD has a capacity of 4 TB and a speed of 15.8 GB/s, and costs only $44. Of course, this is impossible, but the authors still bought an SSD to understand what it is.
You can immediately see that the SSD has only one memory chip, which is not enough for 4 TB. What is very important is the drive’s ability to pass the MediaTester test, which is what usually detects counterfeits with an inflated capacity.
But the CrystalDiskInfo tests put everything in its place. If we compare the 1080 Pro with the real 980 Pro, the latter is 12-59 times faster. Generally speaking, the fake SSD is in some cases slower than external HDDs, although in a number of other tests the speeds are not as low.
We managed to find out that the drive is based on a Realtek RTS5765/66 controller with PCIe 3.0 support and old 96-layer 3D TLC NAND memory from Intel. Unfortunately, it was not possible to find out the storage capacity, but it is clearly quite small.
