NVMe information view

NVMe information is similar to well-known S.M.A.R.T. information provided by hard drives and SATA SSDs. It provides insight into the health and possible problems with an NVMe storage device. However, it is tailored to the properties of flash-based storage, covering NAND memory issues instead of mechanical problems of a rotational hard drive.

What to look for

Reliability degraded and Locked read-only are bad.

Another important thing is Media errors count, which should normally be zero. Small values are acceptable, but keep an eye out that it does not increase.

If any of the above is bad, make an image file of the device.

Thermal management entries can mostly be ignored, except for Critical composite temperature time. You don't want any of that, but there is not much you can do about it if you have it already. If you got some, make an image file of the device, it is literally fried.
