Samsung unveils Universal Flash Storage 4.0, claiming double the speed of UFS 3.1, making it ideal for 5G phones, and sets mass production for Q3 2022
5G smartphones are about to get much faster. — TL;DR — Samsung's UFS 4.0 flash storage will offer twice the performance of 3.1.
Context & Ripple Effects
Samsung’s storage roadmap has progressed from UFS 2.0 NAND for phones and tablets to mass-produced 512GB eUFS 3.0 chips. UFS 4.0 extends that component cycle with a stated performance jump over UFS 3.1 and a Q3 2022 production target.
The 5G positioning matters because Samsung is tying faster on-device storage to the performance expectations of newer smartphones, rather than treating storage capacity alone as the upgrade.
First-order effects
- Samsung adds UFS 4.0 to its mobile-memory roadmap, with mass production scheduled for Q3 2022 and a claimed twofold performance gain over UFS 3.1.
- Phone makers building 5G devices gain a higher-performance storage option from Samsung once volume supply begins.
Second-order effects
- Samsung’s UFS 4.0 claim raises the performance bar for storage components used in 5G phones, pushing handset makers to weigh faster storage alongside other device-memory choices.
- The shift reinforces Samsung’s ability to pair advances in mobile storage with its earlier high-bandwidth LPDDR4X DRAM production, making component performance a broader handset-design consideration.
Third-order effects
- If successive UFS generations continue to arrive alongside new mobile-network capabilities, smartphone differentiation will increasingly depend on the combined performance of storage, memory and connectivity rather than network speed alone.
The trend: Mobile hardware suppliers are moving storage performance forward in step with 5G-era smartphone requirements, making internal data movement a more visible device specification.
