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?
What are your recommendations?
Thanks!

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.
Thanks!
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.
Out of curiosity 
When you installed HA did you do it “the regular way” and then did “Move disk” or you forced the install to NVME as it is described in the manual?
Advanced: Forcing installation onto the NVMe SSD when using CM4 with eMMC:
Press the blue button while the yellow LED is on constantly (during the 5s window, see next step).
I used the RPi imaging tool to load the HAOS Yellow firmware (manually downloaded from GutHub) to my NVME drive that I had temporarily placed into a USB3 enclosure.
Ah, thanks. I used an USB stick created with Raspberry Pi Imager and then followed steps I linked as doing it any other way resulted in files being present on eMMC and NVME.
