Kioxia Launches E1.S SSDs with Liquid Cooling for AI Data Centers
Event summary
- Kioxia introduced the NX1 Series E1.S PCIe 5.0 NVMe SSDs, its first with direct liquid cooling support.
- The new drives offer up to 38% higher sequential write performance and 20% higher random write performance compared to the previous generation.
- Available in capacities from 1.92TB to 15.36TB, targeting GPU-enabled servers and hyperscale data centers.
- Sampling begins with select hyperscale customers, with a product showcase at FMS conference (August 4-6).
The big picture
Kioxia's NX1 Series addresses the growing demand for high-performance, thermally efficient storage solutions in AI-driven hyperscale environments. As data centers increasingly rely on GPU-accelerated workloads, the E1.S form factor and liquid cooling capabilities position Kioxia to capture market share among cloud providers and large-scale operators. The launch underscores the strategic importance of storage density and thermal management in next-generation infrastructure.
