I wrote a series of articles that covered the new features defined for NVMe drives. The general pattern is that there are now lots of optional hints that drives and host systems can exchange about data placement, alignment and lifetime. But there are also alternative paradigms available like Zoned Storage that break compatibility to offer explicit control. These features are mostly only implemented in enterprise SSDs, and often only if a big customer specifically asks for them. https://www.anandtech.com/show/11436/nvme-13-specification-published-new-features https://www.anandtech.com/show/11436/nvme-13-specification-p... https://www.anandtech.com/show/14543/nvme-14-specification-published https://www.anandtech.com/show/14543/nvme-14-specification-p... https://www.anandtech.com/show/16702/nvme-20-specification-released https://www.anandtech.com/show/16702/nvme-20-specification-r... https://www.anandtech.com/show/15959/nvme-zoned-namespaces-explained https://www.anandtech.com/show/15959/nvme-zoned-namespaces-e...
