Professional capacity and speed

This 128GB SDXC card targets professionals and prosumers who shoot with mirrorless and cinema cameras. It delivers read speeds up to 280MB/s and write speeds up to 100MB/s for efficient workflows. The card meets Class 10 and Video Speed Class 60 ratings for sustained performance. Its full-size form factor fits standard SD slots in compatible devices.

Durability features protect data

Water proof, X ray proof, temperature proof and drop proof construction guards files during transport and field use. These protections reduce the risk of data loss from environmental hazards. The card supports cinema-quality 6K and 4K UHD recording at a sustained 60MB/s capture rate. Fast offloads save time when transferring high-resolution footage to editing systems.

Suits high-bitrate video and burst photography

Videographers recording 6K, 4K UHD or Full HD at demanding bitrates benefit from the V60 sustained write guarantee. Photographers capturing continuous bursts or time-lapse sequences gain reliable shot speeds up to 100MB/s. Users needing capacities beyond 128GB or faster write throughput for specialised workflows should evaluate higher-capacity or higher-speed alternatives. Compatibility with UHS-enabled host devices is required for advertised speeds.

Questions about this item

How often should I replace this SDXC card if I use it daily for 6K video?

SanDisk rates the card as water proof, X-ray proof, temperature proof and drop proof, so physical wear is minimal; replace only if you notice write errors or capacity loss.

Will the V60 rating sustain 60 MB/s writes during long 4K UHD clips?

Yes, Video Speed Class 60 guarantees a sustained 60 MB/s capture rate on UHS-enabled hosts, so 4K UHD recording stays within the limit.

Does the card run hot or draw extra power during all-day 280 MB/s read sessions?

The card is temperature proof and has no moving parts, so heat and power draw remain low even during continuous high-speed offloads.
