✓Refresh Pro™ software provides health monitoring, firmware updates and performance refreshing.

✓Write‑protect switch prevents accidental data loss during handling and transport.

✓Backward compatible with UHS‑I and lower‑speed hosts, ensuring functionality across many camera models.

Cons

✗Performance drops significantly when used in devices that only support UHS‑I, limiting its speed advantage.
✗Weight of the card is not specified, which may be a concern for users tracking total equipment mass.
✗No documented consumer feedback or real‑world reliability data, making it harder to assess long‑term durability.
✗Higher price point compared to lower‑tier UHS‑II or UHS‑I cards may be prohibitive for budget‑conscious users.
✗Operating temperature specifications vary between sources, indicating possible inconsistencies in documentation.

Expert Opinion

Professional reviewers are not directly quoted in the available sources; the information consists mainly of manufacturer datasheets and retailer specifications that emphasize the card’s high sustained speeds, durability and suitability for flagship cameras.

What Users Say

No consumer reviews or testimonials were found in the research, so everyday user sentiment cannot be summarized.

How It Compares

vs. Generic UHS‑II V60 SD Card

Advantages

✓Lower price point while still offering UHS‑II bus speed; sufficient for 4K video with 60 MB/s sustained write.

Disadvantages

✗Maximum sustained write speed of only 60 MB/s may limit high‑bitrate 6K/5K RAW capture; lower maximum write speed than ProGrade.

Choose the V60 card for cost‑sensitive 4K work; choose ProGrade for 6K/5K and demanding burst shooting.

vs. Generic UHS‑I U3 SD Card

Advantages

✓Broad compatibility with older cameras and devices; typically cheaper than UHS‑II cards.

Disadvantages

✗Maximum bus speed limited to ~104 MB/s, insufficient for high‑bitrate 4K+ video and fast burst photography.

UHS‑I U3 cards are suitable for older equipment or casual use; ProGrade’s UHS‑II V90 is required for professional high‑speed workloads.
