Review on High-performance NVMe PCIe Adapter: M Key M.2 NVME SSD to PCI-e 3.0 x4 Host 🔌 Controller Expansion Card with Low Profile Bracket - Supports 2230, 2242, 2260, 2280 Sizes for PC Desktop by Scott Gafur

Like many others had problems installing SSD then I looked at pictures and instructions :) I bought this to work around an Optiplex 3070 problem. M.2. Socket only supports PCie 2.0, not 3.0, so speed was limited to around 1700MB. I installed an SSD on the adapter and the system did not see it. Bios didn't report it either. Since this was a clean install I figured I'd try to see if Windows Setup saw it before returning it. I reinstalled the adapter and it worked great. The speed is now 3400 MB.
