Hi together,

I just bought a Home Assistant Yellow for running my smart home, after I have troubles with Matter Devices in my previous VM which run for years.

What is better to run Home Assistant on?

  • Onboard eMMC storage
    or
  • added SSD

What are your recommendations?

Thanks!
Dominik

Hi idominiki,

eMMC is quick and reliable, but I am noticing that people with Blue’s and ODroids are starting to find their chips are wearing out and about ready for replacement this 3-4 years in. Not horrible, but I would have a spare chip. Not as bad an an SDcard.
An SSD you need a hub with an external power supply to make it reliable and not get glitched by or draw down the main power.
I think I would get a big eMMC so lots of room, flash that and use it, have the eMMC it comes with as a spare.

Home Assistant Yellow has an NVMe SSD Slot onboard, so I have the choice between eMMC or SSD

Then NVME 100% would be my choice.

When I set up my HA Yellow, I chose to run everything off of a 1TB Samsung NVME SSD. It has been running smoothly ever since. Since the eMMC on the CM4 is not user-replaceable, I chose to not worry about it being worn out over time. The NVME drive should last for many, many years without having to worry about it.
