What Actually Matters (Before Buying)
1. Video Speed Class (MOST IMPORTANT)

- V60 (60MB/s) → 4K 60fps / high bitrate
- V90 (90MB/s) → Pro video (All-I, RAW, 8K)
2. UHS Type (Speed Interface)
- UHS-I → Enough for most creators
- UHS-II → Faster buffer + pro workflows
3. Capacity (Underrated Factor)
- 128GB = ~2–3 hours of 4K footage
- 256GB+ recommended for serious creators
