It's not as cheap, but you might have better luck with something based off the Espressobin platform, although I can't remember if the switch chip is completely closed source.
The best results were using armbian kernel and userspace for this device. You should be able to build one in a less than an hour on modern pc.
I have a v7 device that I use with a sata drive. It has been stable so far.
Edit: forgot about needing a recent bootloader. This is also mentioned by armbian docs.
