Your droplet does not have an SSD drive, it has an image on the hypervisor (which has the SSD drives). So your droplet can't tell whether TRIM is supported or not and thus does not have to worry about it since it's managed by the hypervisor.

That’s really sad that we still can’t TRIM internal disk, only volumes!

  • Just checked, after removing 15 GB file, despite fstrim reported error, a snapshot takes 3.5 GB, so it seems Hypervisor/snapshot is FS aware.
