All SATA SSDs and almost all NVMe SSDs use 512-byte LBAs by default, but many NVMe SSDs can be reconfigured to use 4096-byte LBAs by default. The underlying NAND flash memory these days typically has a native page size of 16kB.
Thanks. What are the tradeoffs with NVMe sector size? There must be some reason to want 4096 if they added that option. Is there less write amplification as you get closer to the native page size or does the firmware avoid that anyway with its write leveling?
