Review on Ultra-Fast and High-Capacity TC SUNBOW 512GB M.2 NVMe SSD - Unleash the Power of SATA III 6G Technology! by Geoffrey Graham

The first thing I did after installation and formatting was to carry out H2TETW to test the capacity. It worked, and then Crystaldiskmark to note performance. I quickly formatted it as a drive, but didn't read or write anything while using the laptop. It was no longer working after a few days, was displayed in the device manager as a "unknown memory" and nothing was displayed in the data carrier management. I have confirmed it by trying an identical laptop, no change, and when I tried the Transcend 2242 device, the Transcend actually worked and works, so I know that it is not a laptop.
