I see these as pointless technology because you still have to deal with data protection explicitly at a higher level. Given that, what does KV per drive really get me?
You'll get benchmarks that show higher numbers compared to non-KV SSDs and Samsung may use them in its marketing. But yes, key-value APIs are not going to make durability (and security) any easier. It's easier with lower level APIs, i.e. raw flash or some primitive mapping around raw flash, not higher level APIs.
