  i'm not familiar with geany or linuxcnc...  any options
in geany for save interval?

  what kind of file system?  what are the mount options
in fstab?  type of SSD?

  a sync once in a while like other poster recommended
may be a help as it would also clear out any waiting io
but i'm not sure how much that may interfere with the
realtime aspects if you have some large chunks waiting.

  i've used ionice for some things to make sure they
don't interfere on an older system with limited
capacity.  my current machine is a screamer in comparison
so i've not had to do that.
