To make the most of edge AI capabilities in modern robotics, fast, expansive, and durable local storage solutions are imperative. As robots are increasingly able to continuously accumulate data and evolve their capabilities autonomously, they need to be able to read and write that data swiftly and consistently, with complete confidence in its veracity, and reliability. That places much greater demands on storage solutions – exactly the kind of workloads BIWIN’s BGA SSD and Mini SSD were built to meet.
Traditional embedded storage solutions (such as UFS, eMMC, M.2 SSDs, and MicroSD cards) face inherent trade-offs in performance, physical dimensions, and scalability. That makes it difficult for these legacy form-factors to offer what modern robotics requires including high demand workloads, long operational lifecycles, complex system integration, and incremental learning capabilities.
BIWIN’s BGA SSD combines high performance, a compact footprint, and robust shock resistance, making it well suited for integrated storage in robotic systems. BIWIN’s Mini SSD retains the advantage of high performance and small form factor, while introducing a replaceable design that enables flexible capacity expansion.
Together, they form an integrated ‘embedded + expandable’ storage architecture, delivering a complete storage solution for intelligent robots that combines stability, scalability, and system efficiency.
Embedded BGA SSD + External Mini SSD
Supports High-Frequency Data Writes for Advanced Perception and Decision-Making
The core computing board, the ‘brain’ of humanoid robots, serves as the hardware hub for advanced perception, cognitive reasoning, and autonomous decision-making. Powered by high-performance AI processors, it runs multimodal large models and processes massive streams of sensor data in real-time to understand the environment and plan tasks. This process requires high-speed and reliable storage to manage the vast volumes of data continuously generated by humanoid robot sensors, generate continuously, while supporting rapid access to the AI models used across a wide range of operational tasks. BIWIN BGA SSDs are based on a PCIe 4.0 x4 interface, delivering sequential read speeds of up to 7,350 MB/s and capacities of up to 2 TB, enabling a near-instant boot time for the operating system and AI models.
The data write demands of robotic systems far exceed those of typical consumer SSD applications. In certain high-load deployments, daily write volumes can reach up to 300 GB. Once the capacity of the initially configured onboard storage (such as UFS or fixed SSDs) becomes saturated, it can no longer provide sufficient space for continuous data ingestion and model iteration, ultimately limiting the robot’s ability to continuously evolve and risking a degradation of its functions if it cannot further expand its real-world maps or evolve its instructions
BIWIN Mini SSD adopts a SIM-card-style slot design, simplifying storage expansion to a plug-and-play experience. With no device disassembly or specialized tools required, robots can quickly expand up to 2 TB of high-speed storage capacity (with higher capacities planned in future releases), providing a solid foundation for long-term data accumulation, incremental learning, and continuous intelligent evolution. With a single-port design,it is simple to hot-swap a new Mini SSD for additional storage or alternative robotic functions.
BIWIN Mini SSD delivers an optimal balance of ultra-compact design, expansive capacity, and high-performance data transfer. Featuring a PCIe 4.0 x2 interface, BIWIN Mini SSD achieves sequential read/write speeds of up to 3,700 MB/s and 3,400 MB/s, with a clear upgrade path to higher-performance versions in the future (such as PCIe 5.0).
SIM-Card-Sized Form Factor, Weighing Only 1g
Reduces System Footprint and Overall Device Weight
As humanoid robots are increasingly deployed in the real-world at scale, lightweight design goals are becoming increasingly important. It helps lower manufacturing and shipping costs, improves robotic mobility, and expands application possibilities. As an essential hardware component, the size and weight of the storage module directly influences the overall system design of the robot, directly correlating to its eventual size and weight
BIWIN’s BGA SSD and Mini SSD feature an ultra-compact footprint roughly the size of a coin, with a package thickness as thin as 1.4 mm. The Mini SSD, weighing as little as 1 g, can be directly inserted into a reserved socket, significantly reducing constraints on system layout and overall device weight. In humanoid robots designed for high dynamic performance and extended endurance, BIWIN BGA SSDs and Mini SSDs deliver powerful capability in a micro form factor, enabling more compact systems and greater motion flexibility.
Dual Storage Synergy Streamlines Component Procurement and Integration
Safeguarding Storage Across the Entire Robot Lifecycle
BIWIN’s Mini SSD is an expandable storage module that delivers value far beyond basic storage functionality. Its modular and standardized design philosophy introduces a new architectural approach for robotics, laptops, and other intelligent devices.

User Value: Plug-and-Play, Flexible Storage Expansion
With no tools or specialized expertise required, users can easily perform on-site storage expansion or replacement. Designed for reliable repeated insertion and removal, BIWIN Mini SSDs allow end users to seamlessly expand or replace TB-level storage, improving end-user control and device upgradeability.
Paired with BIWIN’s proprietary RD510 card reader (USB4.0 Type-C supported), BIWIN’s Mini SSD provides high-performance, portable storage for a wide range of scenarios, including mobile productivity and content creation.
The BIWIN Mini SSD is in mass production and has been built into a range of smart handheld gaming devices, including OneXPlayer X1 Air, Fly APEX, Super X, and GPD WIN 5, and is now commercially available in the consumer market. The MINI SSD’s capabilities have also received international recognition, earning multiple prestigious awards, including TIME “Best Inventions of 2025”, and Embedded World 2025 “Best-in-Show”. It was also honored as an Edison award winner in 2026 in the Engineering & Robotics category, and received recognition at CES 2026 by winning the TWICE Picks and Avrona Most Innovative awards.
BIWIN is now collaborating with multiple SoC platform providers and leading device manufacturers to advance the standardization of the Mini SSD interface and ecosystem, accelerating its large-scale adoption in cutting-edge fields such as AI terminals and humanoid robotics. It’s proved its capabilities with existing devices, now it’s ready for what comes next.
