What SSD is compatible with Lenovo LOQ 15IRH8 (2023-2024)?

The Lenovo LOQ 15IRH8 (2023-2024) supports M.2 PCIe NVMe drives with standard single-sided PCBs. Slot 1 accepts M.2 2280 form factor. Aftermarket drives with thick pre-installed aluminum heatsinks will not allow the chassis cover to close.

Can I install a double-sided SSD in Lenovo LOQ 15IRH8 (2023-2024)?

No. The Lenovo LOQ 15IRH8 (2023-2024) has strictly <=2.38mm underside clearance. Double-sided SSDs (chips on bottom) will bend against motherboard components.

Critical Mechanical Clearance Warning

CRITICAL CLEARANCE ALERT: Lenovo LOQ chassis has strictly <=2.38mm underside clearance. Double-sided SSDs (such as Kingston KC3000, WD SN850X 4TB, or Corsair MP600 Pro) have NAND chips on the bottom that will press against the motherboard PCB traces, risking short circuits and physical bending.

Heatsink Interference Rule:Do NOT purchase aftermarket SSDs with thick aluminum heatsinks (e.g., Samsung 990 Pro with Heatsink). The laptop case will NOT close. Re-use the factory pre-installed thermal shield or apply a thin 0.5mm copper shim.
