I have both, an ALIX and an APU. Alix is at the end of life, and it will struggle with torrents and and big load. Also speed is 100M that may be ok on most connections. I am not sure about newer then 2.4G cards. Also is hard to find adaptors to write the SD card for ALIX.
ZS doesn’t come with all drivers for these little devices so you may need some additional work.
I compiled all drivers, (or almost) for APU2 ( I have an apu2c4) I also did some mods as a hobby. ( added 8 LEDs )
I used a 16g msata ssd + one vle200 ( 2.4G N ) and one vle600 ( 5G AC )
Unless u want to play around and you get an alix for cheap I would recommend APU2.
APU1 may be ok, I just don’t have experience with it.
I’ve decided to go with the APU2c2. In my experience I’ve never seem ZS memory usage over 1GB, have you ever seen more usage than 2GB on your APU2c4?
So are just LED and GPIO drivers missing in ZS3.7.1?
Does the wle200 work without mods?
Do you find the APU2 stable?
Also, I’ve just used USB to boot ZS in a small PC. Considering ZS runs in memory do you see any performance (or other benefit) installing ZS to mSATA in the APU instead of USB?
