I'm not even sure what you are referring to there.
I am not going to claim, I understand the matter fully. This
is my source

My understanding is, a hdd is told by the system when to read and
write data. A hdd will not autonomously start altering and
optimizing the data. According to the article and a radio show
talking about the matter, ssds are different. The ssd
has build in software which can independently start moving
data and write it onto the ssd. If the data is decrypted
what can happen is the encryption software can
lose track of such data and get unable to encrypt or
shred the data.
The article mentions the manager of veracrypt. He says,
he is not going to utilize a ssd for anything involving
encryption. I cannot say, if the matter also applies
for usb memory sticks.
In order to get to know if a ssd can compromise
encrypted data as described, the ssd software would have
to be made public and get audited. But ssd manufactures
are not going to make the software in question
public.
When I got aware of this matter, I expected it would
get a big story. But it did not. When I mentioned
the matter here and there, then I got no response
or brushed of. No one made a technical convening
rebuff about the matter.
