Benchmarks: Storage
We're predominantly looking at the top half of the board here - speed emanating from the CPU rather than chipset. Sequential speeds of 5GB/s are easy for PCIe 4.0-toting B550.
It's a shame that no board here features the fastest iteration of USB offering 20Gbps. At least Riptide offers 10Gbps from both the front-panel connector and a couple of ports on the rear. It's high time the baseline for all USB ports was 10Gbps.
