I don't have scientific benchmarks but I did observe noticeable performance differences in data ingestion workflows between a machine with a SATA 3 drive and a machine with a NVMe drive (and it was a mid-range one, with 2200/1700 MB/s speeds). But the gains are only coming if you properly setup the machine, e.g. a NVMe drive can't make much use of its high concurrency stats if you don't have a strong multicore CPU with a newer motherboard that allows for more traffic.
