   Here's the output of your script tested on my Pi5 with NVMe SSD:   
      
      READ: bw=850MiB/s (891MB/s), 850MiB/s-850MiB/s (891MB/s-891MB/s), io=10.0GiB   
   (10.7GB), run=12046-12046msec   
     WRITE: bw=746MiB/s (782MB/s), 746MiB/s-746MiB/s (782MB/s-782MB/s), io=10.0GiB   
   (10.7GB), run=13727-13727msec   
      READ: bw=64.6MiB/s (67.7MB/s), 64.6MiB/s-64.6MiB/s (67.7MB/s-67.7MB/s),   
   io=1937MiB (2031MB), run=30000-30000msec   
      READ: bw=223MiB/s (234MB/s), 223MiB/s-223MiB/s (234MB/s-234MB/s), io=6684MiB
