   I think the Radxa Pi4 one was released just before all the supply chain   
   mayhem when nobody could buy Pi 4s - I think they discontinued it so I'm   
   not sure it's actually available right now.  On the Pi 4 you have to use USB   
   rather than PCIe, unless using a Compute Module (when you lose USB3).   
      
   I'd expect PCIe to be more stable under load than USB.  They use a JMB585   
   PCIe to SATA chip which isn't enterprise grade but seems to work well   
   enough.  Since Pi5 doesn't lose USB3, you can get 2.5G networking via a $10   
   USB adapter, rather than Jeff's odd PCIe switch.   
      
   The Pi4 was just a bit compromised for this use case IMO, but it looks like   
   the Pi5 plus this HAT gets most things right.
