Description and Notes
This card requires external power (and includes a molex to floppy power adapter), but works great on both the Raspberry Pi CM4 and Pi 5 model B.
Note that certain devices can behave strange when run behind a PCI Express switch / bridge. Notably, NVMe drives cannot be used as boot drives on the Compute Module 4 behind a switch (and it remains to be determined if they will work on the Raspberry Pi 5 behind a switch).
