   Remember, I'm testing nvme on an Orange Pi 5 not a Raspberry Pi 5, but,   
   I feel quite inadequate. However, it is what I get.   
      
   Here are the results from druck's script:   
      
      READ: bw=200MiB/s (209MB/s), 200MiB/s-200MiB/s (209MB/s-209MB/s),   
   io=6000MiB (6291MB), run=30060-30060msec   
      WRITE: bw=199MiB/s (209MB/s), 199MiB/s-199MiB/s (209MB/s-209MB/s),   
   io=6000MiB (6291MB), run=30085-30085msec   
       READ: bw=36.0MiB/s (37.8MB/s), 36.0MiB/s-36.0MiB/s   
   (37.8MB/s-37.8MB/s), io=1081MiB (1133MB), run=30001-30001msec   
       READ: bw=48.1MiB/s (50.4MB/s), 48.1MiB/s-48.1MiB/s   
   (50.4MB/s-50.4MB/s), io=1443MiB (1513MB), run=30001-30001msec   
      
      
   Maybe my result is so bad because I'm only using a KingSpec nvme drive?   
   It's supposed to do 3500MB/s, but I've never tested it in anything that   
   could handle that.   
      
   I'm not going to use a top range drive on a Pi. The Orange Pi isn't   
   doing anything else, isn't busy.
