HomeAssistant Yellow NVME compatibility

Hardware
,
21

Observations:

  • PCIe Generation Compatibility: SSDs utilizing PCIe Gen 3.0 tend to work reliably with Home Assistant Yellow. In contrast, some PCIe Gen 4.0 SSDs, such as the WD Black SN770 and Kingston NV2, have been reported as non-functional.
  • SATA vs. NVMe: SSDs designed for SATA, like the Transcend 240GB M.2 SSD 820S, are incompatible, as Home Assistant Yellow supports only NVMe SSDs.
  • Specific Models: Certain models, including the Samsung 980 Pro 1TB and Verbatim Vi3000 256GB, do not function correctly, despite meeting general specifications.

Good: Silicon Power NVMe SSD (128GB tested, other sizes should be fine)

I got mine from the same place I got the Yellow, This isn’t a referral link, it was just the easiest way to provide more info.

23

I tried the Samsung model (MZ-V7S1T0B/AM) and my HA Yellow didn’t recognize it. I’ll try another one and see if I just ended up with a bad one the first go-around

24

Good: SSD M.2 2280 KIOXIA Exceria G2 2TB 3D TL - LRC20Z002TG8

25

Good: just bought ADATA Legend 710 PCIe Gen3 X4 M.2 2280 SSD 1TB / 2N4229AAQKAX and it just works. Just installed it, let’s see if it will run smoothly.

Hello,
does anyone know if this model works: Samsung SSD 990 Pro NVMe M.2 PCIe 4.0 ( MZ-V9P1T0BW)?

27

I am using a CM5 with emmc.

Good: Silicon Power (SP) A60 256GB NVMe M.2 PCIe Gen3x4 2280 SSD (SP256GBP34A60M28)
Bad: KingSpec SSD NX-512 512GB M.2 NVMe 2280 PCIe Gen 3.0X4

28

I just got Kioxia Exceria G2 (1TB), but it does not work.

It is M.2, so it should work. Has anybody tried that storage? Maybe it has a defect.

29

Bad: Western Digital 1TB Blue SN580, M.2 2280 PCIe Gen 4.0 (WDBWMY0010BBL)

This might’ve been a different model number of WD 1TB Blue SN580 that worked for bwaller (Gen 4.0 vs. Gen 3.0), or perhaps there’s another issue. As of yet, no SSD has been recognized by this machine.

ConsistentBottle5632 confirmed with a CM5 with emmc, I’ve confirmed with CM4 with an HA Yellow:

Good: Silicon Power (SP) A60 256GB NVMe M.2 PCIe Gen3x4 2280 SSD (SP256GBP34A60M28)

31

Hi there, had you succeeded with MZ-V7S1T0B/AM? I tried 2 different pieces of this model, but none worked for me. Seems that 1TB is not supported. Interestingly, some other people reports that it works. I contacted support, but they are not responding.

32

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.

33

LOL this thread is all over the place… whats the dysfunction in the NVME industry that makes compatibility such a problem?

I just read the faq on ssd compatibility for the yellow with cm4, but i have a cm5, is there a similar faq for it?

34

Same here! Just starting with HA and opted for HA Yellow with a PI CM5. I’m about to buy the Samsung 990 PRO 1TB M.2 NVMe SSD. Is it compatible or should I look for another one?

35

Worked: Samsung PM9A1 512GB, M.2 2280 Nvme SSD, Model MZ-VL25120, Part # MZVL2512HCJQ-00BH1

Using: Home assistant yellow hardware version 1.3 with CM5
Running Home Assistant version Core 2025.4.3
Supervisor 2025.04.0
Operating System 15.2
Frontend 20250411.0

Booted the system and then moved using the GUI using the Home Assistant process here. Actual move took about 2 minutes since I don’t have much data to move. eMMC no longer available in the GUI but the system still shows it via the “All hardware dialogue" under “mmcblk”. SSD shows under “nvme”.

Hardest parts were: Knowing to use a hex metric 1.5mm (they said 1mm and I was searching everywhere for one… but then I just removed it with my fingers and later learned that 1.5mm works ok). Later use a star PH1 bit for the bottom. The translucent bottom part of the case on the bottom, the board just sits on it, it’s not attached.

36

Hi, has anyone tried Kingston NV3 with CM5?

37

The Home Assistant Yellow is not compatible with the Pi Compute Module 5 (CM5).
It was designed specifically for the Compute Module 4 (CM4) The CM5 has different power, I/O, and physical layout specifications and will not work in Yellow’s carrier board

38

That is incorrect. The HA Yellow DOES work with the CM5.
There are some differences in functionality (e.g. USB booting), but as soon as HAOS is installed, it works.
Official HA Yellow documentation about installing a CM5 and flashing the OS

UPD. It does work fine
