UHS-I vs UHS-II: What’s the Difference (and Why it Matters for Capturing Summer Memories)

Summer is finally here, and whether you're jetting off to a tropical destination, embarking on an epic road trip, or simply exploring new spots around your hometown, capturing high-quality photos and videos is essential for preserving those priceless memories.

But if you've recently shopped for SD cards, you've likely encountered confusing terms like UHS-I and UHS-II. Wondering what they mean, why it matters, and which is the best choice for your DSLR, video camera, or drone? Let's break it down and see how choosing the right one can elevate your summer travel experience.

What Exactly is UHS?

Ultra High-Speed (UHS) refers to the bus interface standard for SD memory cards, essentially determining how fast your SD card transfers data. It’s crucial when working with high-resolution photos and videos that modern devices capture.

There are two popular standards you'll encounter: UHS-I and UHS-II. UHS-I offers transfer speeds up to 104 MB/s, suitable for everyday photography and basic HD video recording. On the other hand, UHS-II significantly boosts performance up to 312 MB/s, thanks to an additional row of pins designed for higher speed data transfer. If you're frequently capturing 4K videos, RAW photos, or bursts of images, UHS-II is the way to go.

Does My Device Support UHS-II?

Many newer cameras from brands like Nikon, Sony, Olympus, Fuji, and Panasonic support UHS-II, allowing creators, prosumers, and videographers to fully leverage these faster speeds. However, not every device includes built-in UHS-II support, which can cause frustration when trying to quickly offload your vacation footage onto a computer or tablet. That's where our latest Satechi products come into play, seamlessly bridging the gap.
