   That surprises me, could anyone with an NVMe base run this script which   
   measures the maximum sequential and random access read/write speeds.   
   You'll need to install the fio package and be in a directory on the disc   
   under test.   
      
   #!/bin/bash   
   TESTFILE=fio-tempfile.dat   
   fio --name SeqRead --eta-newline=5s --filename=$TESTFILE --rw=read\   
     --size=500m --io_size=10g --blocksize=1024k --ioengine=libaio\   
     --fsync=10000 --iodepth=32 --direct=1 --numjobs=1 --runtime=30\   
     --group_reporting | grep bw=   
   fio --name SeqWrite --eta-newline=5s --filename=$TESTFILE --rw=write\   
     --size=500m --io_size=10g --blocksize=1024k --ioengine=libaio\   
     --fsync=10000 --iodepth=32 --direct=1 --numjobs=1 --runtime=30\   
     --group_reporting | grep bw=   
   fio --name RndRead --eta-newline=5s --filename=$TESTFILE --rw=randread\   
     --size=500m --io_size=10g --blocksize=4k --ioengine=libaio --fsync=1\   
     --iodepth=1 --direct=1 --numjobs=1 --runtime=30 --group_reporting\   
     | grep bw=   
   fio --name RndWrite --eta-newline=5s --filename=$TESTFILE--rw=randwrite\   
     --size=500m --io_size=10g --blocksize=4k --ioengine=libaio --fsync=1\   
     --iodepth=1 --direct=1 --numjobs=1 --runtime=30 --group_reporting\   
     | grep bw=   
   rm $TESTFILE

   More than dd'ing the SD card image on to the NVMe, using gparted to   
   expand the linux partition, and then changing the boot device in   
   /boot/cmdline.txt and /etc/fstab ?
