Question about Samsung 9100 PRO

No, in your PCI 4.0 notebook the 9100 PRO does not provide a higher maximum sequential speed than the 990 PRO, as it is limited to PCIe 4.0 and is equally fast there. In sequential reads with Q1 (close practice), however, it is still almost 50% faster than the 990 PRO, and the random performance is superior. In benchmarks on PCIe 4.0 it achieves approx. 7100 MB/s read and 6990 MB/s write, just like the 990 PRO at the limit.
