Why do you care?firecuda 510's E12 controller replaced with E12S?
The only entity that could reliably answer your question is Seagate. All units after serial number X might be the "S" controller for example.I wondered
I'm using vlo e12si it doesn't recognize it, but I don't remove the label because it will be out of warranty and there is also an m2 heatsink on it.
also this is not an answer, if i asked an answer is necessary related to the topic
