Ah I see the disconnect, TRIM doesn’t live in the OS outside of the firmware, TRIM is part of the controller firmware and is exposed as an ATA command for the OS to utilize
The study I have linked in my original comment goes more in-depth
Yes, I know.
I’m on a phone, and it only partly showed up.
Direct PDF link
I mean, I read the PDF, the problem was the viewer bogging down.
googles
This sounds like what I expected:

EDIT: I took a look at your PDF on a desktop. While it’s pretty light on the specifics of how they tested that the data was present, nothing there talks about anything below the OS level. My expectation is that what they did for their test was try to do reads from the device at the OS level and see whether it returned zeroes. They aren’t going to look below that. If they were interfacing with the drive at a firmware or below level, I’d expect them to have mentioned it, as it’d be a significant amount of additional work. And they don’t list relevant information like model number, much less firmware revision on the drive.
This is a complete digression but do you know if there is a consumer hardware that can be reliably erased? I’m trying to make something behave as an affordable HSM. If I could store a key encrypted at rest and be able to actually delete it, that would work for me.
Like, to create a hardware keystore? No, I don’t, sorry. If I wanted one myself, I’d probably just buy an existing one and hope that they did things correctly. :-)
