Oh sorry. I was a bit imprecise.
There are 3 types of SMR drives:
1.drive managed: SMR device manages all requests. Performance is
unpredictable in some workloads. Backward compatible.
2.host aware: host uses new commands & information to optimize write
behavior. If host sends sub-optimal requests the SMR device accepts the
request but performance may become unpredictable. Backward compatible
3. host managed: host uses new commands & information to optimize write
behavior. Performance is predictable. If host sends sub-optimal requests
the SMR device rejects the request. Not backward compatible
