Maybe CrystalDiskInfo is simplifying things (combining TRIM and the mentioned DEALLOCATE command?), but all my NVMe SSDs support TRIM according to it. And it would be really strange if NVMe didn't support any sort of trimming, as SSD performance and health heavily relies on it.
It could also be that what the author is observing is specific to macOS?
- doubled112 2y agoThe controllers on many USB SATA adapters don’t support TRIM.
- TonyTrapp 2y agoThat I'm aware of, but the claim is that TRIM does not exist for NVMe drives.
- gruez 2y agoRE: TRIM vs DEALLOCATE, that seems to be a naming thing. Wikipedia confirms that it's indeed technically DEALLOCATE on nvme. https://en.wikipedia.org/wiki/Trim_(computing)#NVM_Express https://en.wikipedia.org/wiki/Trim_(computing)#NVM_Express
