ProGrade 128GB SDXC V30 UHS-I Memory Card

The ProGrade Digital 128 GB SDXC UHS-I V30 Memory Card is designed for creators needing reliable, high-performance memory for photography and video. With a UHS-I bus interface and V30 / U3 / Class 10 rated speed class, it supports continuous shooting, burst stills, and high-resolution video including 4K. According to the official listing, the card achieves read transfer speeds up to ~200 MB/s and write speeds up to ~50 MB/s for the 128 GB capacity.
Available as a Single Pack (one 128 GB card) and a 2-Pack (two identical 128 GB cards bundled) — the performance per card remains the same, the 2-Pack simply gives you a pair for dual-slot workflows or redundancy.

Key Features

• Capacity: 128 GB (per card).
• Bus / form-factor: SDXC, UHS-I interface.
• Speed class: V30, U3, Class 10 — guaranteeing a minimum sustained write speed of 30 MB/s.
• Read speed: Up to ~200 MB/s.
• Write speed: Up to ~50 MB/s (specs listed for 128 GB model) though some sources claim up to ~90 MB/s for certain batches/capacities.
• Built for professional use: includes features like built-in write-protect switch, durable construction (resistant to shock, X-rays, temperature extremes) per manufacturer claim.

Best Suitable

• Photographers shooting in burst mode or RAW who need reliable write speeds and large capacity.
• Videographers working with 4K or high bit-rate Full HD footage needing sustained performance without dropped frames.
• Content creators using UHS-I compatible DSLR or mirrorless cameras that accept SDXC cards and need fast off-load/transfer speeds.
• Users wanting dual-card redundancy or swapping workflows — the 2-Pack option is ideal for backup or simultaneous slots.

FAQ – ProGrade 128GB SDXC V30 UHS-I Memory Card

What’s the difference between the Single Pack and the 2-Pack?

There is no technical performance difference per card — both variants are the same 128 GB specification. The 2-Pack simply gives you two cards in one bundle, making it useful for dual-slot cameras or backup workflows.

Will it work in my camera?

You must confirm your camera supports SDXC (not just SDHC) and uses the UHS-I bus. While UHS-I is widely supported, ensure your slot is not limited to slower SD speeds. Also check that your workflow demands roughly the performance this card offers (read up to ~200 MB/s, write up to ~50 MB/s).

Why is the write speed only ~50 MB/s but the read speed much higher?

For many UHS-I SDXC V30 cards, especially lower capacities like 128 GB, manufacturers list read speeds more aggressively (up to 200 MB/s) whereas write speeds reflect more conservative sustained performance. The V30 rating ensures at least ~30 MB/s sustained write, which is suitable for 4K capture.

If I use a slower card reader, will my transfer speeds suffer?

Yes, To fully leverage the read speed of ~200 MB/s, you’ll need a card reader capable of high UHS-I speeds and a USB/host interface that supports those speeds. Slower readers will bottleneck the card’s potential.
