How to determine if SSD is faulty

[balanga]

I recently installed a brand new 4TB SSD and after two week, I am getting ZFS error.

How should I test it? I presume smartmontools would hghlight any shortcomings.

What should I look at?

What other tools are worth considering?

Install smartmontools and run `smartctl -x /dev/$disk`

LLM's like ChatGPT turn out to be very good at interpreting the results.

The only reliable way to determine true SSD health status is to use manufacturer provided diagnostic tools. Unfortunately, in many cases, that requires Windows. All on one diagnostic tools can give false positive results and they should be avoided. They just read S.M.A.R.T status, and thats not always reliable when it comes to SSDs.

For NVMe SSDs on FreeBSD, you can use in-base nvmecontrol(8) instead.
But smartctl(8) via sysutils/smartmontools would be using same data internally, so no differences with reliability / dependability. The reliability / dependability and not mandatorily standardized data formats are mostly on manufacturers.
