Solid-state drives sound ideal as they have no spinning parts and are very quiet, but they have a limited lifespan as you can’t write a memory cell only an X amount of times. But how to check your SSD on Linux to see if it is still in good shape? S.M.A.R.T. has become the standard for disk health years ago and can be queried by
smartctl. So if we query for the health status and show all available attributes we get a good overview.
The most interesting attributes are 202 on how much lifetime is left, but also 5, 180, and 9 that show you the number of replaced storage cells and how many hours the disk has been running. If attributes 5 and 180 are changing it is most definitely time to replace this solid-state drive as memory cells have been worn out.
