What the selected M.2 slot must support

The documented NVMe interface and M.2 2280 length can be compared with a specific board slot. This is a specification comparison, not a hands-on detection or boot test.

For an M.2 drive, check whether the board slot is CPU-connected, shared with a PCIe/SATA port or restricted by the selected processor. The official board manual governs those conditions.

Physical and firmware checks

Heatsink clearance, mounting hardware, firmware detection and boot mode are separate from a nominal connector match. Review the exact drive and board documentation before purchase.
