PCIe slots offer meaningful advantages over M.2 slots for PC expansion. Key benefits include higher bandwidth (up to PCIe 4.0 x8 at 128 Gbps vs. M.2's typical x4 at 64 Gbps), greater power delivery for demanding cards, and easier cooling due to better orientation and larger surface area. M.2 is fine for Wi-Fi, USB, and SATA cards, but PCIe slots are the better choice for high-performance expansion like secondary GPUs, multi-SSD NVMe adapters, or HBA cards.
