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
