title: SSD Trim on Linux
body: <p>I heard a lot of different opinions about SSD Trim and normally it's not very important to know how that is handled because you know that is handled unless I use systems where most of the installation steps are manual like Arch Linux.</p>
  
  <p>The Arch Linux documentation does explain few ways to configure SSD Trimming, continuous, periodic... etc. but it does not say if the kernel is doing trimming by default on a supported filesystem without any additional configuration step.</p>
  
  <p>Can I safely skip manual configuration of continuous or periodic trim found in the documentation? How do I monitor those kind of operations? Would I be safe on a clean installation using a kernel 5+ and ext4 as fs without using any of those approaches explained on the documentation?</p>

  <p>Should I be worried in the long term because I never trimmed an SSD disk when Arch Linux silently pretended to be healthy for so long?</p>
