Installed with no problems on M2 slots and with a PCIE adapter card. Using with Windows Storage Spaces and ReFS file system. No clearance problems with the heat sink (the tapered edges are an advantage).
This thing was really easy to install (although I did have to order an extra screw because the one that comes provided for use in the PS5 was stuck). This thing is super fast going from PS5>SSD, going the other way though it is slower, maybe 2-4 times slower.
