write-amplification

Flash SSD Simulator! This simulator allows you to experience the inner workings of a flash-based Solid-State Drive (SSD) right from your web browser. Whether you're a student studying computer architecture or a curious tech enthusiast, this simulator provides a hands-on understanding of the key operations and concepts related to flash SSDs.

Python page-mapped NAND flash translation layer simulator modeling out-of-place updates, greedy garbage collection, and write amplification under workloads.

Reducing SSD Write Amplification by 48% via Hot/Cold data separation in FEMU Blackbox FTL — WAF 7.67 → 3.94

Hand-written LSM storage engine in Go: WAL, deterministic crash recovery, leveled compaction, write-amplification meter. Standard library only.

Log-structured key-value engine for zoned storage (ZNS / libzbd, host-managed zones). Cuts host write amplification up to 29x vs a conventional baseline; crash-safe via zone write pointers. C++20 on Linux null_blk.
