No, that's the weird thing. Even the RMA models were failing. But sure enough, it wasn't just some incompatibility with the NAS because I tested them on PCs to confirm they were failing, and they were.
I had a similar experience. I ordered four EXOS drives three years ago and one of them came DOA. They had to send me three more drives before I got a working one. I’m amazed they’re all still happily humming away in a Synology.
