Built for 8K workflows

This SDXC card targets professional photographers and cinematographers who need sustained write performance for cinema-quality 8K video recording and high-resolution continuous shooting. The V90 rating guarantees a minimum sustained write speed of 90MB/s on compatible devices, while peak read and write speeds reach up to 300MB/s. It suits creators who cannot afford dropped frames or buffer bottlenecks during critical capture moments.

Sustained write reliability

The V90 class ensures the card maintains at least 90MB/s write throughput during extended recording sessions, preventing buffer overflow when shooting 8K at 30 fps or 4K UHD at 60 fps. With 128GB capacity, you can record up to 286 minutes of 8K footage or 352 minutes of 4K UHD 60 fps video before offloading. Fast buffer clearing at up to 300MB/s write keeps the camera ready for the next burst.

Rugged environmental protection

Rated IP68 for water and dust resistance, the card survives immersion and particulate exposure common on location shoots. It is also tested to withstand drops from up to 19.6 feet, adding physical durability for demanding field conditions. RescuePRO Deluxe recovery software is included free for two years to restore accidentally deleted or corrupted files.

Questions about this item

How much heat or power does the 300MB/s write speed draw during all-day 8K recording?

The card is IP68 rated for water and dust resistance and tested to survive 19.6-foot drops, so it is built to handle sustained workloads without thermal throttling.

What host device do I need to actually reach the V90 90MB/s sustained write speed?

You need a camera or recorder that supports the UHS-II interface and V90 video speed class; the card delivers up to 300MB/s write only on such devices.

Will this 128GB card work in my older UHS-I camera body?

Yes, it is backward compatible with UHS-I slots, but write speeds will be limited to the host's maximum rather than the card's 300MB/s peak.
