Used to do recycling. Before secure erase was widespread there used to be cheapish 16 and 32GB SSDs for embedded devices, but a few of them made it into the thin/zero client space and a few white labelled low end pc's. they were actually twice the size. Basically 2 16s in a single 16 chassis. And what you would get is that the 2 drives were sort of in sync, I think it was a failover mechanism to deal with shitty drive quality. If drive A failed it would just connect to drive B instead and the user might not know about the failure. But the second drive would not wipe necessarily depending on how you wiped the first one. A few people retrieved data from the second disk under lab conditions, after wiping the first, so we had a report come through that we couldnt certify these disks as erased until they demonstrated compliance with secure erase. So we shredded probably a few thousand of them. I heard of similar issues with early nvme drives.
