TOKYO, Oct 10 (Bernama-BUSINESS WIRE) — Kioxia Corporation, today announced an expanded RocksDB plug-in that enhances SSD lifespan and performance in multi-drive RAID environments. Building on its earlier demonstration of a Flexible Data Placement (FDP)-enabled SSD running RocksDB, the company will showcase this advancement at the upcoming Open Compute Project (OCP) Global Summit.
In a 4-drive RAID 5 setup, Kioxia’s new plug-in reduced write amplification factor (WAF) by approximately 46% and boosted throughput to 8.22x the performance of MDRAID¹. In a 2-drive mirrored configuration, WAF was reduced to approximately 1/3 and achieved throughput of 1.45x compared to MDRAID¹. The technology achieves these gains by consolidating data writes so they are written sequentially – preventing data fragmentation and reducing garbage collection.
