- Adoption of UFS in SBCs is growing as manufacturers like Rockchip and MediaTek integrate UFS support into their SoCs, with storage capacities now reaching up to 1 TB.
- Challenges such as hardware limitations and higher costs remain, but UFS is poised to replace eMMC as the standard storage solution, with broader implications for compact computing and beyond.
Understanding Universal Flash Storage (UFS)
Universal Flash Storage (UFS) is a high-speed NAND flash storage technology initially developed for mobile devices but now finding its way into SBCs. Designed to deliver faster data transfer rates and lower power consumption, UFS addresses the increasing demands of modern computing environments. Over the years, UFS has evolved through several iterations, each offering improved performance and efficiency:
- UFS 2.0 (2013): Marked the first major leap in storage performance, setting the stage for future advancements.
- UFS 3.1 (2020): Introduced features such as Write Booster for enhanced write speeds and deep sleep mode for improved energy efficiency.
- UFS 4.1 (expected in 2025): Promises even greater speed and efficiency, further solidifying UFS as a leading storage solution.
UFS 3.1, the current standard in many devices, offers theoretical read speeds of up to 2,100 MB/s. This makes it a compelling choice for SBCs, where both performance and power efficiency are critical. Its ability to handle demanding tasks while consuming less energy positions UFS as a superior alternative to traditional storage options.
Comparing UFS to Traditional SBC Storage
Historically, SBCs have relied on eMMC storage due to its affordability and simplicity. However, eMMC is limited in speed, with typical read speeds rarely exceeding 200 MB/s. This creates bottlenecks for modern applications that require faster data access. While NVMe SSDs offer significantly higher speeds, they often face hardware constraints in SBCs, such as limited PCIe lanes or older PCIe versions, which restrict their performance.
UFS bridges this gap by offering a middle ground. With its high-speed capabilities and efficient design, UFS 3.1 delivers a substantial performance boost over eMMC while avoiding some of the hardware limitations associated with NVMe SSDs. This makes UFS an attractive option for compact computing devices, allowing them to handle more advanced workloads without the need for complex hardware configurations.

Real-World Performance: UFS on the Rock 4D SBC
To evaluate the real-world performance of UFS, a 128 GB UFS 3.1 module was tested on the Rock 4D SBC. The results demonstrate the impressive capabilities of UFS technology:
- USB 3.0 Reader: Achieved read speeds of 826 MB/s, showcasing the module’s ability to deliver high-speed performance even through external interfaces.
- Native UFS Interface: Delivered read speeds of 1.1 GB/s and write speeds of 273 MB/s, significantly outperforming eMMC storage and rivaling some NVMe SSD setups.
These results highlight the potential of UFS to enhance storage performance in SBCs. However, they also reveal a key limitation: current SBC hardware cannot fully exploit UFS 3.1’s theoretical maximum speeds. This underscores the need for further advancements in SBC design to unlock the full potential of UFS technology.
Expanding UFS Adoption in SBCs
The adoption of UFS in SBCs is closely tied to the compatibility of the system-on-chip (SoC). Leading manufacturers such as Rockchip, MediaTek, and Qualcomm are integrating UFS support into their SoCs, paving the way for broader adoption. Notable examples include:
- Rockchip RK3688: A SoC designed with UFS compatibility, allowing faster and more efficient storage solutions.
- Radxa Dragon Q6A: A MediaTek-based SBC that supports UFS modules, demonstrating the versatility of this technology.
UFS modules are now available in a range of capacities, with options reaching up to 1 TB. This flexibility allows users to choose storage solutions tailored to their specific needs, whether for general computing tasks or data-intensive applications. As more manufacturers adopt UFS technology, its presence in the SBC market is expected to grow, offering users a wider array of high-performance storage options.
Challenges and Future Prospects
Despite its many advantages, UFS adoption in SBCs faces several challenges:
- Hardware Limitations: Many SBCs lack the ability to fully use UFS’s maximum speeds, limiting its immediate impact on performance.
- Cost: UFS modules are more expensive than eMMC, which may deter budget-conscious users from adopting this technology.
However, the future of UFS in SBCs looks promising. As SoC manufacturers continue to enhance UFS support and SBC designs evolve, UFS is poised to replace eMMC as the standard storage solution for compact computing devices. Its potential to rival NVMe SSDs in performance further underscores its value, particularly for ARM-based systems. This evolution could enable SBCs to handle more advanced computing tasks, from AI processing to high-resolution media playback, with greater efficiency and reliability.
Broader Implications of UFS Technology
The benefits of UFS are not limited to SBCs. Its adoption is expanding into other compact computing devices, including x86 mini PCs and cloud-based systems. For instance, Microsoft’s 365 Link Cloud PC uses UFS storage to deliver fast and reliable performance in a small form factor. This broader adoption highlights the versatility of UFS and its potential to become a standard for high-performance, energy-efficient storage solutions across various computing platforms.
As UFS technology continues to mature, its impact on the computing landscape is expected to grow. By offering a combination of speed, efficiency, and scalability, UFS is well-positioned to meet the demands of modern computing, paving the way for faster and more efficient devices in the years to come.
