Over-provisioning is doable since more 15" laptops and motherboards are starting to have 2 NVMe slots, and you always could've gotten additional PCIe->NVMe slot

Over-provisioning is doable since more 15" laptops and motherboards are starting to have 2 NVMe slots, and you always could've gotten additional PCIe->NVMe slots for a motherboard.
