| Feature | UFS 4.0 | NVMe (PCIe 4.0/5.0) | |----------------|----------------------------|----------------------------| | Peak speed | ~4.2 GB/s | up to 14 GB/s | | Power efficiency | Excellent (mobile-first) | Moderate to high | | Max capacity | 1TB (common) | 8TB+ | | Heat management | Passive, low | Active cooling often needed | | Use case | Phones, embedded | PCs, servers, consoles |
UFS 4.0 now rivals entry-level NVMe drives in speed. But NVMe still wins for sustained workloads and capacity. Meanwhile, UFS 4.0 beats NVMe in power-per-byte — critical for all-day phones.
Which one do you use daily? 👇
