Boot Device status is degraded - on new m2 SSD

[mindgam3s]

Hello there,

maybe you can help me out.
I just bought a WD Green m2 SSD as primary boot device in order to have a more reliable way of storing the boot data than using USB sticks which really tend to fail fast sometimes.

anyways, I installed the latest stable freenas (10.2) on the m2 SSD and everythintg seems fine.
after booting into the system with no problem I get the alert in the upper right corner that my boot device status is DEGRADED with an error resulting in data corruption.

EDIT: I even tried the latest stable freenas 10.0

I was worried and installed Windows 10 just to check whether everything is alright. running some tools to verify disk integrity resulted in everything beeing okay from windows side.

so I installed freenas again, same alert.

Can I rely on that message being wrong or is there any known bug when using m2 SSDs ?



Please help me out :x

It's a known issue with some SSDs, e.g.:

thanks for the quick reply! I couldn't find anything when googling for this topic...

how can I know which SSDs are fine and which are not?

You'll need to google it or search the forum, I only know the Trasncend S370 and Intel 320 work OK, since those are the ones I used.

is there any m2 SSD that has been tested with freenas and works fine?

are there some manufacturers that are more reliable than others?
I dont know where to start looking for a fitting m2 ssd

It appears some SSD controllers are more affected than other, Samsung devices should work fine since they use their own, but never tested.
