Pro-grade SDXC card for 8K video

The SanDisk Extreme PRO SDXC card delivers 512GB of storage built for cinema-quality 8K recording and high-resolution stills. It carries a V90 rating that guarantees a minimum sustained write speed of 90MB/s when used with compatible devices. Maximum write and offload speeds reach 300MB/s to keep professional workflows moving fast. This card targets creators who need reliable capacity and speed for demanding productions.

Sustained write performance under load

The V90 rating ensures the card maintains at least 90MB/s write throughput during long takes rather than only in short bursts. Peak write speeds of 300MB/s help clear the camera buffer quickly during continuous high-speed shooting. With 512GB capacity the card holds up to 286 minutes of 8K video at 30 fps or 352 minutes of 4K UHD at 60 fps. Consistent throughput prevents dropped frames and recording interruptions on set.

Rugged IP68 build with drop protection

The card is IP68 rated for water and dust resistance and survives drops from up to 6 meters (19.6 feet). This ruggedisation lets professionals work in harsh weather and unpredictable environments without worrying about media failure. A built-in write-protect switch prevents accidental data loss during handling. The durable construction suits daily field use where reliability is as critical as speed.

Questions about this item

How much heat or power draw should I expect from this 512GB V90 card when recording 8K video continuously?

As a passive SDXC card it has no active cooling or power draw of its own; heat and power depend entirely on the host camera during sustained 300MB/s write operations.

What host device features are required to reach the 300MB/s write and 90MB/s sustained V90 speeds?

You need a camera or reader that supports the SD UHS-II interface and V90 video speed class; without both the card will fall back to lower speeds.

Will this UHS-II V90 card work at full speed in my older UHS-I camera body?

It is backward compatible but will operate at UHS-I speeds in a UHS-I slot, so you will not see the 300MB/s write or 90MB/s sustained V90 performance.
