3 Things to Know About the ASUS PN51’s Single M.2 Slot

Only one drive fits at a time The PN51 has a single M.2 slot, so you can install either an NVMe or SATA SSD, but not both simultaneously.

No second M.2 or other internal storage The compact design leaves no room for a second M.2 slot or any other internal drive expansion.

Choose your drive type carefully Since you’re stuck with one slot, pick the SSD that best balances speed and capacity for your needs — NVMe for faster performance, SATA for lower cost.
