Technical Notes

  • You may install any number of SSDs now and add more later without needing to reformat existing ones. This product’s performance will vary based on the type and number of SSDs used, the CPU speed, and the PCIe architecture.
  • macOS 13 and macOS 14 do not currently support NVMe SSDs installed in a PCIe slot of the Mac Pro 7,1 (2019). Sonnet is working with Apple to resolve the issue.
