They are now available as commercial samples in 1 TB and 512 GB capacities*. Mass production is expected to begin in late 2026.

Based on the latest JEDEC UFS 5.0 standard, KIOXIA's new devices leverage the MIPI M-PHY v6.0 physical layer and the UniPro v3.0 protocol, including HS-Gear6 operating mode, to support theoretical interface speeds of 46.6 Gb/s per lane and an effective dual-lane read/write throughput of approximately 10.8 GB/s.

As AI workloads continue to migrate to devices, storage performance is becoming increasingly critical. Large language models, multimodal AI, advanced image processing, and real-time inference all require significantly faster data transfer between storage and the compute unit.

Until now, UFS read performance has been a limiting factor for increasingly sophisticated on-device AI, restricting how quickly large language models (LLMs) and other AI workloads could access data. KIOXIA's UFS 5.0 helps eliminate these bottlenecks, enabling faster application loading, greater responsiveness, and an exceptional user experience across all on-device AI applications, compared to UFS 4.1.

KIOXIA's UFS 5.0 solutions combine a proprietary UFS 5.0 controller with KIOXIA's eighth-generation 3D BiCS FLASH™ flash memory, delivering significant improvements in performance, power efficiency, and packaging compared to the previous generation of KIOXIA products(2), including:
10 GB/s sequential read performance(3),
9.0 GB/s sequential write performance(4),
increased power efficiency compared to the previous generation(2),
improved thermal management, and
a compact 7.5 × 13 mm BGA package, smaller than the previous generation product(2).
Available in 1 TB and 512 GB capacities.

While optimized for high-end smartphones with integrated AI, KIOXIA's UFS 5.0 is also well-suited for AI tablets, gaming consoles, AR/VR devices, robotics, smart security cameras, and cutting-edge industrial applications. that require fast local storage for data-intensive AI workloads.

“On-device AI is redefining what users expect from future mobile devices and edge devices; manufacturers need storage solutions that can keep pace with these growing AI workloads,” said Axel Störmann, Vice President and Technical Director of KIOXIA Europe GmbH. “Since AI workloads require fast and efficient data access, KIOXIA’s UFS 5.0 offers the speed, efficiency, and capacity needed to develop these next-generation smart devices.”
