Penta SATA HAT Kit for Rock Pi 4

Hey Radxa team,
Will there be a Penta SATA kit for Rock Pi4? There’s currently only a Quad SATA Kit for Raspberry Pi 4.

I believe the holes on the aluminium case does not match the Rock Pi 4, as the Rock Pi 4 layout matches the Raspberry Pi 3.

Also, is the Quad SATA HAT bottlenecked by the USB 3 Bus at 5Gbps?
