> Today I consider myself lucky to get storage with 4K sectors and I recall seeing rumors that game console SSDs would ship with far larger erase blocks. The erase blocks on current NAND flash are already up to 16+MB, while the page sizes are typically 16kB. So even presenting the illusion of 4kB sectors requires a lot of extra background work from the SSD controller, and that's been true for generations. Also, the NVMe Streams feature is from the 1.3 spec in 2017: https://www.anandtech.com/show/11436/nvme-13-specification-published-new-features https://www.anandtech.com/show/11436/nvme-13-specification-p... Like most of the more advanced NVMe features, it's targeted at enterprise or datacenter use cases and most of the initial adoption is among the hyperscale cloud providers that have the resources and incentive to optimize their IO stack from top to bottom.
