Thanks; yes, it certainly does. I'll save it for later though because I've had 
another idea. This box was made by Armari, a company that makes high-
performance workstations for financial firms in the City, where milliseconds 
count, apparently. They delivered it with their standard overclocking setup: 
4GHz instead of 3.3. I set it back to 3.3 but today I've put the 4GHz settings 
back in to see if the machine can now keep up with the NVMe (if that is indeed 
my problem).
