On June 21,2021 I purchased  Dell Optiplex 5050 Small Form Factor (SFF) Business Desktop PC, Intel i7-7500 Quad-Core 3.6 GHz, 16GB DDR4, Intel 512GB PCIe NVMe SSD Windows 10 Pro (Renewed)About a week ago the main storage drive died.  I discovered it is Kingfast brand, an apparently disreputable bottom of the barrel company based on reports on the internet. The product description said it would be an Intel brand SSD. I lost months of data in addition to the drive and Windows 10 operating system which I cannot recover because you did not put a product key on the computer.
