Key Takeaways
1. JEDEC has been standardizing flash memory since 2011, focusing on Universal Flash Storage (UFS) for smartphones and tablets.
2. UFS 4.0, introduced in 2022, offers transfer speeds of up to 5,800 Mbps using two lanes, with UFS 5.0 promising even higher speeds of 10,800 Mbps.
3. While UFS 5.0 narrows the speed gap with top PCIe SSDs, smartphones still lag behind the fastest laptops in terms of storage speed.
4. UFS 5.0 is expected to be more reliable and easier to integrate into devices, featuring improvements in signal integrity and enhanced security.
5. Real-world performance of UFS 5.0 may vary, as seen with UFS 4.0 devices that do not always achieve their maximum potential speeds.
Since 2011, the JEDEC industry group has been working on standardizing flash memory for gadgets such as smartphones and tablets, which depend on Universal Flash Storage (UFS) rather than PCIe. UFS 4.0 was introduced in 2022, boasting transfer speeds of 2,900 Mbps on a single lane and 5,800 Mbps when using two lanes. Now, UFS 5.0 is almost complete and is expected to deliver even greater speeds.
New Speed Expectations
JEDEC has announced a peak speed of 10,800 Mbps for UFS 5.0. To put this into perspective, top-tier PCIe 5.0 SSDs, like the Samsung 9100 Pro (starting at $128 on Amazon), can reach around 14,700 Mbps. Although smartphones are still behind the quickest laptops, the difference is narrowing. JEDEC emphasizes that this enhanced storage capability will be essential to satisfy the increasing needs of AI applications.
Reliability and Integration
UFS 5.0 is anticipated to be more dependable due to improvements in signal integrity. It is also designed to be simpler to incorporate into devices thanks to a distinct power supply for the signaling unit and storage subsystem, while inline hashing bolsters security. As has been the case in the past, it may take a few years for this new UFS standard to become widely available, and even then, UFS 5.0 does not assure faster storage speeds. For instance, the Google Pixel 10 Pro with 256GB of storage or more uses UFS 4.0, but in our detailed assessment, the smartphone only achieved relatively low data rates of up to 1,492 Mbps, while rival devices typically perform more than twice as fast.
Conclusion
Overall, the advancements in UFS technology show promise for the future of mobile devices, but consumers should remain cautious as real-world performance can vary significantly.
