ProGrade Digital Iridium V90 UHS-II SD 128GB
An enthusiast-tier UHS-II SD card (128GB, V90, 300 MB/s read) whose V90 rating targets the consistent sustained writes that 4K and 6K recording needs. It's a value-minded pick for shooters on UHS-II bodies who want reliable video write speeds without jumping to CFexpress. A sensible mainstream choice; cameras needing CFexpress or higher capacity should look further.

Verdict
Best for
- UHS-II cameras shooting 4K/6K video
- consistent sustained-write recording
- value-focused enthusiast shooters
Who should skip this
- UHS-I-only cameras — the second pin row goes unused, so you overpay for speed
- Casual JPEG shooters — V90 sustained write is overkill below 4K/6K video
- High-capacity needs — 128GB is modest for long-form 6K days
