smr drives are horrible. we have some here. some by accident, others for cost savings (used only for long term, large file storage)--but all of smr's faults are really not worth it.. maybe at half the price per tb it might be--for some use cases, but not at current pricing.
the last batch we got in don't even support trim, so i guess the only way to 'clean up' zones is to literally dump everything off, secure_erase them, and 'start over'.
TRIM is SSD technology and SMR is spinning-disk technology, you wouldn't find them on the same drive, would you? 🤔 Or do you mean a hybrid drive?
