Hi,
As the RPi 5 4Gb is in short supply can anyone provide feedback on how the 2Gb model performs?
Proposed build:
RPi 5 2Gb
Raspberry Pi DAC Pro
Waveshare M.2 Adapter with Active Cooler for Raspberry Pi 5
KKSB Case for Raspberry Pi 5 and Raspberry Pi DAC+ and DAC Pro Sound Cards
SSD (M.2 2230-format NVMe)… when the price comes down!
Inside Raspberry Pi 5 - 2GB RAM / Khadas Tone 2 Maker / USB - SATA adapter with 2.5 cal 1 TB SSD SATA - Mean Well 5V - 5A power supply.
Working OK.
2GB is fine for Home Assistant 
It’ll run your setup smoothly (HA + DAC + NVMe), just avoid heavy add-ons. 4GB mainly just gives more breathing room, not speed.
Hey @dadadac
Hardware choice boils down to the individual use case. If you are looking for assistance I think this summary will be helpful:
Kind Regards,
I have 1 GB / 2GB / 4GB Rpi5 at the moment and here’s my take.
1GB is more than enough if you are not going to enable Kiosk mode at all. Accessing web ui from another device is perfectly fine. Playing music is also excellent and it barely uses 50% of RAM when playing music.
2GB is when you have an external display attached to it and need to enable Kiosk mode. I add a 4K TV to it and it can operate properly, as long as the screen resolution is 1920X1080 or less. 4K is a bit too much. Also make sure Chrome hardware acceleration is enabled (Volumio team can help with it), via the /opt/volumio-kiosh.sh file flags
4GB is a gross overkill and has no effect on performance, since the issues come with HW acceleration being disabled not CPU or RAM. I think 2GB is best since the price difference between 1GB and 2GB is like $10-15 at most.
Once you get it up and running, you can install btop++ on it to monitor CPU / RAM etc.
