TOKYO -- Kioxia Corporation, 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 MDRAID[1]. In a 2-drive mirrored configuration, WAF was reduced to approximately 1/3 and achieved throughput of 1.45x compared to MDRAID[1]. The technology achieves these gains by consolidating data writes so they are written sequentially - preventing data fragmentation and reducing garbage collection.

RocksDB, widely adopted for generative AI and cloud applications, is optimized for high-performance searches and efficient management of historical data.

The new plug-in will be featured with the KIOXIA XD8 Series SSD in a live demonstration at the Kioxia booth (A51) during the 2025 OCP Global Summit. The demo will showcase performance gains and reduced WAF in a two-drive RAID 1 configuration with the RocksDB plug-in, compared to standard Linux™ RAID mirroring.

Kioxia will release the plug-in as an open-source contribution, underscoring its commitment to advancing SSD and flash memory technologies industry-wide. By sharing innovations that improve efficiency, Kioxia continues to support the evolving needs of advanced computing infrastructures and data centers. The new plug-in is expected to be released in CQ1 2026.
