256GB SDXC UHS-II V90 card

The Patriot Memory V90 provides 256GB of storage for cameras that support the UHS-II interface and V90 speed class. It targets professional photographers and digital filmmakers who capture 8K or 4K ULTRA HD video and high-speed sequential burst modes. The exFAT format ensures broad compatibility with modern recording devices. This card is not suited for hardware limited to UHS-I speeds or lower video speed classes.

UHS-II slot and exFAT host required

The card fits devices equipped with a UHS-II SD card slot and an operating system that reads exFAT, such as Windows 7, 8.0, 8.1 or 10. Fast read speeds up to 300MB/s free up post-production time when offloading large footage. Write speeds up to 260MB/s sustain continuous recording without dropped frames. Built-in wear leveling and bad block management protect flash longevity during heavy use.

Sustained V90 performance under load

The V90 rating guarantees a minimum sustained write speed of 90MB/s during long recording sessions, not only in short bursts. Sequential burst-mode shots continue without slowdowns because the controller maintains throughput across the full capacity. Shock, vibration, temperature and waterproof construction preserves data integrity in harsh shooting environments. The card complies with SDA 6.1 and earlier specifications for reliable interoperability.

Questions about this item

At what write speed does the V90 rating guarantee the card will not drop frames during long 8K bursts?

The V90 rating guarantees a minimum sustained write speed of 90 MB/s, which is the threshold for continuous 8K and 4K recording without dropped frames.

How much power does the card draw and does it get hot during all-day 4K video shoots?

SD cards draw very little power from the host device and the card is rated temperature proof, so it stays cool during extended recording sessions.

Which camera slot and file system are required to reach the 300 MB/s read and 260 MB/s write speeds?

You need a camera with a UHS-II SD slot; the card comes formatted exFAT, which supports the large files created at those speeds.
