Can I add a second SSD to ASUS Zephyrus G14 (2024)?

NO. The 2024 Zephyrus G14 only possesses 1x M.2 2280 NVMe SSD slot. To expand storage, you must replace the factory SSD with a larger single-sided drive (e.g. 2TB or 4TB Samsung 990 Pro / Lexar NM790).

What SSD fits in ASUS Zephyrus G14 2024?

Only single-sided M.2 2280 PCIe 4.0 x4 NVMe SSDs (<=2.2mm thickness) fit. Double-sided drives like Kingston KC3000 will bend the motherboard or prevent the aluminum bottom shell from snapping closed.
