256GB microSDXC for action cameras

This Lexar High-Performance 633x card provides 256GB of storage for smartphones, tablets and sports camcorders. It captures, plays back and transfers 1080p full-HD, 3D and 4K video files quickly. The UHS-I U1 Class 10 rating supports sustained write performance for continuous recording. Buyers who need more capacity or faster sustained write speeds for professional cinema workflows should look elsewhere.

UHS-I bus limits transfer ceiling

The card leverages UHS-I technology with a read speed up to 95MB/s and a write speed up to 45MB/s. The 633x rating indicates a maximum transfer rate of 100MB/s under ideal conditions. Real-world throughput will be lower due to bus overhead, host controller limits and file-system fragmentation. Devices restricted to the older Class 10 interface without UHS-I support cannot reach these speeds.

Verify host device supports microSDXC UHS-I

Check that your smartphone, tablet or action camera accepts microSDXC cards up to 256GB and can utilise the UHS-I bus for full performance. Some older models only recognise microSDHC or cap capacity at lower limits. An SD adapter is included for use in full-size SD slots. Ensure firmware is current to avoid compatibility issues with high-capacity cards.

Perguntas sobre este artigo

Should I pick the 256GB 633x card or a smaller capacity for my phone?

The 256GB capacity holds far more 4K clips and apps than smaller sizes, while the 633x rating still delivers up to 95MB/s reads and 45MB/s writes for smooth recording.

Will the 95MB/s read speed actually move 4K footage off the card that fast in my laptop?

Real-world offloads typically hit the rated 95MB/s over a decent UHS-I reader, so a 256GB card full of 4K files clears in minutes rather than tens of minutes.

Does the UHS-I U1 Class 10 rating limit write performance in my action camera?

U1 guarantees a minimum 10MB/s sustained write; the card can burst to 45MB/s, so 1080p and 4K recording stays stable without dropped frames.
