Configuration constraints / exclusions
  • The PSREF explicitly documents up to two drives, with one 2.5-inch HDD and one M.2 SSD 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.
  • Optional Intel Optane Memory is listed as PCIe NVMe 3.0 x2.
