The NUC 12 Extreme / Pro X Kit provides the following Storage interfaces:
- Two internal PCIe Gen 4 x4 M.2 NVMe/SATA slots supporting M.2 2242/80 on the NUC 12 Extreme / Pro X Compute Element.
- One CPU-Attached internal PCIe Gen 4 x4 M.2 NVMe only slot located on the NUC 12 Extreme / Pro X Element.
The PCH provides independent SATA ports with a theoretical maximum transfer rate of 6 Gb/s. A point-to-point interface is used for host to device connections.
Figure 4 shows the locations of the M.2 slots.
The Front Side M.2 slots are capable of double-sided M.2 devices while the Rear Side M.2 slot is limited to single-sided M.2 devices.
