Cosa definisce il decreto direttoriale del 15 maggio 2025?
UFS 4.0 is the leading embedded storage standard for smartphones and mobile devices in 2025, known for doubling data transfer speeds compared to the previous UFS 3.1 generation and providing significant efficiency improvements for next-generation use cases such as 5G-connected devices, AI, automotive systems, and high-performance consumer electronics [1] [2] [4].
Key specifications and features of UFS 4.0 in 2025:
- Data Transfer Speed: Up to 23.2Gbps per lane (46.4Gbps per device), representing roughly double the interface speed of UFS 3.1 [1] [2].
- Real-world Performance: Sequential read speeds around 4,200MBps and write speeds of 2,800MBps; improved power efficiency by roughly 45%, enabling faster, slimmer devices [4] [8].
- Capacities & Packaging: Up to 1TB capacity is available, common storage configurations now start at 256GB, and the small form factor (e.g., 9mm x 13mm BGA packages) contributes to sleeker mobile devices [2] [4] [7].
- Backward Compatibility: UFS 4.0 is backward compatible with UFS 3.1, facilitating easy upgrades in existing product platforms [1] [2].
- Enhanced Features: Includes HS-LSS (High-Speed Link Startup Sequence) for faster booting/wake times, Multi-Circular Queue (MCQ) for efficient multitasking, and advanced WriteBooster features for faster, more flexible write acceleration [1].
- Security: Improved Replay Protected Memory Block (RPMB) for more robust and faster secure data erasure and protection [1].
- Applications: Widely adopted in 2025 for smartphones (including leading models from Samsung, OnePlus, Xiaomi, and others [3] [5]), as well as in automotive systems (for real-time sensor/data processing), gaming consoles, AR/VR devices, and industrial applications [1] [4] [10].
A few examples of smartphones using UFS 4.0 storage in 2025 include the Samsung Galaxy S25 Ultra, OnePlus 13 series, Poco F7 5G, and the Xiaomi Redmi Turbo 4 Pro, with prices ranging based on brand, features, and storage configurations [3] [5].
UFS 4.1, an incremental update, was announced in January 2025 and adds further optimizations but retains backward compatibility with UFS 4.0 systems [1] [2].
