Such deletions presumably also entail subsequent TRIM commands.
Thanks for the explanations.

If I monitor static data only on a SSD it is easy to see what triggers a TRIM command.

• Delete to recycle bin = no
• Empty recycle bin = yes
• Temporary files = yes
• Manual TRIM command from the Intel Toolbox = yes
• Save and edit a word document = yes

It seems that a TRIM command is issued as soon as something is marked for a permanent delete.

If the SSD does not immediately act on the TRIM command it would have to store it until it could be executed, which seems unlikely.
