A typical PCIe 4.0 NVMe drive hits sequential read. UFS 3.1 tops out around 2,100 MB/s – faster than SATA SSDs, but less than half of NVMe.

NVMe (PCIe 4.0): ~7,000 MB/s sequential reads. UFS 3.1: ~2,100 MB/s max.

NVMe wins on raw speed. UFS 3.1 wins on power efficiency and small footprint. Different jobs."

NVMe is significantly faster than UFS 3.1 in almost every metric, but UFS 3.1 is optimized for mobile power efficiency.

NVMe for performance, UFS for mobile. 🔥📱💻 #nvme #ufs31 #techcomparison Option 2: Detailed table & summary (blog post / comparison article) Title: NVMe vs UFS 3.1 Speed: Which Storage Interface Is Faster?

Here’s content tailored for different platforms and purposes, comparing (common in PCs, high-end laptops, PS5) and UFS 3.1 (common in flagship smartphones, automotive, some ultra-portables). Option 1: Short-form content (Instagram/TikTok/YouTube Shorts script) Visual: Split screen – left side NVMe SSD, right side smartphone chip.

But UFS 3.1 wins on power efficiency – crucial for phones. NVMe would drain your battery in hours.

| Metric | NVMe (PCIe 4.0 x4) | UFS 3.1 | |--------|--------------------|---------| | Max sequential read | ~7,000 MB/s | ~2,100 MB/s | | Max sequential write | ~5,000 MB/s | ~1,200 MB/s | | Random read (4KB) | ~800k – 1M IOPS | ~100k – 200k IOPS | | Random write (4KB) | ~600k – 1M IOPS | ~70k – 150k IOPS | | Interface | PCIe (3.0/4.0/5.0) | MIPI M-PHY | | Duplex | Full duplex (read+write simultaneously) | Half duplex | | Power efficiency | Lower (higher active power) | Higher (better for battery) | | Typical use | PCs, consoles, servers | Smartphones, tablets, dashcams |

NVMe vs UFS 3.1 – Who’s faster?

"NVMe and UFS 3.1 both use PCIe technology, but here’s the speed breakdown.

But check random read – NVMe might do 1M IOPS, UFS 3.1 around 100K IOPS. That’s why your PC loads games instantly and your phone feels fast, but not that fast.

That’s >3x faster for NVMe. But speed isn’t everything.

So: NVMe for raw speed (PC/PS5). UFS 3.1 for balanced mobile speed.
