HATs and other add-ons • Re: SSD hat and SATA hat together

Can you add a SATA hat and SSD hat to a Raspberry Pi 5?

No. There is only one PCIe lane available.

Actually you can but you need to add a PCIe switch between the PI5 and the two HATs. And you may need to disable the EEPROM probe and do some manual configuration.

I'd recommend a suitable bridge to connect the SATA drives through USB.

Seconded but for a different reason: more bandwidth per device if one of them is on USB 3.

@OP: booting from SATA is not supported. IIRC booting from NVMe behind a PCIe switch is on recent firmware. If both devices connect via USB not PCIe things should just work.
