Question about Kingston A2000

I only took the PCIe-SSD into use a few days ago. When I unpacked it, I could not find any clues that it could be B-ware; the further installation also proceeded without any other problems. I was guided in my product decision by the c't article in the 11/2019 issue. Compared to the SATA SSDs in 2.5 inch format, the M.2 slots with PCI-e connection have to be paid a price premium. The speed advantage of the top models with PCI-e SSDs of over 3 GB/s compared to the SATA interface of 600 MB/s only has an effect in special applications. Therefore, the price for a top product from Samsung, Corsair or a WD Black Edition was too expensive for me and I chose a middle ground. Similarly, WD differentiates in performance and price with the Black Edition and the Blue Edition. With the Kingston A2000, I only get half the possible throughput of a top PCI-e SSD, but the price is on a par with a SATA SSD. A clean system design was a priority: with a modular power supply unit, I could do without the cable harness with the SATA connectors altogether and the SATA cable to the mainboard was also omitted.
