Tokyo: 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.

According to BERNAMA News Agency, in a 4-drive RAID 5 setup, Kioxia's new plug-in reduced the write amplification factor (WAF) by approximately 46% and boosted throughput to 8.22 times the performance of MDRAID¹. In a 2-drive mirrored configuration, the WAF was reduced to approximately one-third, achieving a throughput of 1.45 times compared to MDRAID¹. The technology achieves these gains by consolidating data writes so they are written sequentially, preventing data fragmentation and reducing garbage collection.
