A full guide of UFS 2.2 vs. UFS 3.1 in smartphones

When shopping for a new smartphone like a rugged smartphone, you'll often encounter terms like UFS 2.2 and UFS 3.1 in the specifications. These refer to the type of storage technology used in the device. Understanding the difference between UFS (Universal Flash Storage) versions can significantly impact your decision, especially if performance is a priority. This guide will take you to explore the differences of UFS 2.2 and UFS 3.1 storage technology in smartphones.

First, let's learn about what is UFS memory.

UFS 2.2: The Basics

UFS 2.2 is an upgraded version of UFS 2.1, offering some enhancements in speed and efficiency. Here are the key features:

• Sequential Read Speed: Up to 850 MB/s
• Sequential Write Speed: Around 250 MB/s
• Enhanced Write Booster: UFS 2.2 includes a feature called Write Booster, which uses SLC (Single-Level Cell) caching to accelerate write speeds, especially for large files.
• Low Power Consumption: UFS 2.2 is designed to be power-efficient, making it ideal for mid-range smartphones where battery life is crucial.

UFS 3.1: The Next Level

UFS 3.1 is a significant leap forward in storage technology, offering much faster speeds and additional features. Here are the highlights:

• Sequential Read Speed: Up to 2100 MB/s
• Sequential Write Speed: Around 1200 MB/s
• Deep Sleep Mode: UFS 3.1 includes a Deep Sleep mode (similar to power saving mode), which reduces power consumption when the storage is idle, improving battery life in high-end smartphones.
• Enhanced Thermal Control: UFS 3.1 manages heat better, ensuring consistent performance even during intensive tasks like gaming or 4K video recording.
• Performance Throttling Notification: This feature alerts the system when the storage is too hot, helping to prevent thermal throttling and maintaining optimal performance.

UFS 2.2 vs. UFS 3.1: Key Differences

1. Speed

Read and Write Speeds: UFS 3.1 is significantly faster than UFS 2.2. For example, the read speeds of UFS 3.1 can be more than double those of UFS 2.2. This means apps load faster, and data-intensive tasks like file transfers or video editing are much quicker.

Real-World Performance: In everyday use, UFS 3.1 can reduce lag, shorten app load times, and make the phone feel more responsive, particularly in high-performance scenarios like gaming.

2. Power Efficiency

Battery Life: Both UFS 2.2 and UFS 3.1 are designed with power efficiency in mind, but UFS 3.1 has additional features like Deep Sleep mode, which further reduces power consumption during idle times.

3. Thermal Management

Heat Control: UFS 3.1 includes better thermal management, which is crucial for maintaining performance in high-end devices that are often used for gaming, streaming, and other demanding activities.

4. Future-Proofing

Longevity: UFS 3.1, being the newer and faster technology, is more future-proof. If you plan to keep your phone for several years, a device with UFS 3.1 might better handle future apps and updates that demand higher performance.

Which One Should You Choose?

• Mid-Range Phones: If you're looking at a mid-range device, UFS 2.2 is likely more than sufficient. It provides good performance and power efficiency at a lower cost.
• High-End Phones: For flagship devices or if you're a power user who values speed and performance (e.g., gaming, heavy multitasking, video editing), UFS 3.1 is the better choice. The significant improvements in speed, power efficiency, and thermal management make it worth the investment.

Conclusion

Understanding the differences between UFS 2.2 and UFS 3.1 can help you make a more informed decision when purchasing your next smartphone. While UFS 2.2 offers good performance for most users, UFS 3.1 is the better choice for those who need or want the best possible performance from their device. Whether you prioritize speed, efficiency, or future-proofing, knowing these details will help you choose the phone that best meets your needs.
