Right now the PCIe 4.0-based NVMe drives are maxing out at about 7GB/sec, so we should expect up to 14-16GB/sec or so from PCIe 5.0-based NVMe SSDs of the future. Most PCIe 4.0 SSDs come are on the PCIe 4.0 x4 interface and can still pump away at 7GB/sec, so a PCIe 5.0 x4 SSD should offer around 14GB/sec.

PCIe 4.0 x16 has up to 32GB/sec of bandwidth available while the next-gen PCIe 5.0 standard will double that up to a huge 64GB/sec that will leave 16GB/sec for the x4 interface -- perfect for next-gen PCIe 5.0 NVMe SSDs.
