Drive Notes
The Lenovo ThinkPad E14 Gen 4 (Intel) Laptop Supports Single and Dual Drive Configurations. (Two M.2 NGFF (2242) Solid State Drives) Note: There are two M.2 slots on the system board, slot-1 (SSD1) is for M.2 2242 PCIe Gen4.0 x4 Drives and slot-2 (SSD2) is for M.2 2242 PCIe Gen3.0 x4 Drives. M.2 Drives with PCIe Gen4.0 x4 performance installed in slot-2 (SSD2) will be downgraded to closer to PCIe Gen3.0 x4 performance due to the M.2 slot limitations.
