Configuration constraints / exclusions
  • The PSREF explicitly documents up to two storage drives, with one M.2 SSD and one 2.5-inch HDD able to coexist.
  • M.2 2242 and M.2 2280 are alternative SSD configurations and do not imply two M.2 physical slots.
  • M.2 2280 may use SATA 6Gb/s or PCIe NVMe 3.0 x4; the installed PCIe x4 device runs at x2 due to the documented adapter limitation.
  • The PSREF explicitly lists Optical as None.
  • Optional Intel Optane Memory is listed as PCIe NVMe 3.0 x2; it does not establish another physical M.2 slot.
