Just starting with Home asssistant and opted for HA Yellow with a PI CM5. I’m about to buy the Samsung 990 PRO 1TB M.2 NVMe SSD, but I found a Forum thread about Samsung SSDs not being compatible with HA:
https://community.home-assistant.io/t/homeassistant-yellow-nvme-compatibility/547618/32
The official HA Yellow documentation page only mentions SSDs for the Pi CM4:
https://yellow.home-assistant.io/faq/#which-ssds-are-supported

Is there an official SSD guide for CM5?

No, I ended up just getting the 500 GB version and it worked first try. Should be plenty of storage - only used 2% thus far.

The 970 Evo Plus is good enough, cheaper and compatible.
Haven't heard anything about the 990 Pro, but the 980 Pro had issues.

Is the 1 tb a bit overkill for HA? Should I go with 500gb?

#

The price difference between the 1tb and 500gb is basically negligible

It always depends on what you are doing with it. If you are storing camera for example.

#

I am storing 30 days of backups (1.6-1.8 GB each), am using a 1 TB SSD and just 8.7% are used.
