Modern Storage Engines: LSM-Trees vs B-Trees on High-Speed NVMe Storage

A deep storage systems internals guide comparing Log-Structured Merge-Trees and B+ Trees. We evaluate write amplification, read latency tail distributions, NVMe random vs sequential I/O, and storage tiering across RocksDB, WiredTiger, and PostgreSQL.
