1.3 Usage Notes

- Use of the onboard DisplayPort will reduce the bandwidth available to the M.2SSDsand may impact
their performance.

- Does not supoort Dual-Mode DisplayPort (DP++), however it does support Multi-Stream Transport
(MST) in Windows 10.

- All four drive bays are bootable on macOS. SSDs with 512 byte sectors require macOS 10.13 or later
