Wiki thread for compiling a list of confirmed PCIe SATA SSD adapters for MP5,1 with macOS. They're not as fast as NVMe, but they're widely available. Should also be helpful with options for transition to MP7,1 and (should) achieve faster read/write speeds with native PCIe 3 availability for adapters that support.
