You've got four NVMe drives you want to run at full Gen4 speed, but the signal degrades over the board traces and you're losing throughput you paid for. This retimer adapter sits between your CPU lanes and those drives and cleans up the signal so each port actually delivers Gen4 integrity. Four ports, no lane-sharing headaches, no dropped links under load. Drop it in, seat the drives, and stop wondering why your I/O numbers don't match the spec sheet
