Kioxia America has announced an expanded RocksDB plug-in designed to improve the operational efficiency and endurance of solid-state drives (SSDs) in multi-drive RAID configurations. The plug-in, which will be demonstrated with Kioxia XD8 Series SSDs at the 2025 Open Compute Project Global Summit, targets data center environments where reducing write amplification and increasing throughput are critical.
According to Kioxia, in a four-drive RAID 5 setup, the new plug-in reduced write amplification factor by 46 percent and delivered throughput that was 8.22 times higher than standard MDRAID implementations. In a two-drive mirrored RAID 1 configuration, write amplification was cut to one-third and throughput increased by a factor of 1.45 compared to MDRAID. The improvements are achieved by consolidating data writes for sequential writing, reducing data fragmentation and minimizing the need for garbage collection.
Kioxia describes RocksDB as a key-value database commonly used in generative artificial intelligence and cloud infrastructure, optimized for fast search and management of historical data. The company reports that live demonstrations at the 2025 OCP Global Summit will highlight performance benefits and reduced write amplification using the plug-in and the XD8 Series SSD in RAID 1 environments, compared with standard Linux RAID mirroring.
The plug-in is planned for release as an open-source project in the first calendar quarter of 2026. Kioxia states this move is intended to help advance SSD and flash memory technologies for data center applications and advanced computing infrastructures.
