SanDisk Extreme 256GB microSD

The SanDisk Extreme SDSQXH9-256G-GZ6MA is a 256GB microSD card built for enthusiasts and creators who need fast, reliable storage. It carries A2, U3 and V30 ratings and delivers read speeds up to 245MB/s and write speeds up to 170MB/s over the UHS-I interface. The card is designed to handle 5.3K and 4K UHD video recording in action cameras, drones and Android devices.

Suited for high-bitrate capture

This card suits users recording 5.3K point-of-view footage, 4K UHD aerial video or high-resolution burst stills who need sustained write performance. The A2 rating helps apps load quickly on Android devices, laptops and handheld gaming consoles. Buyers who need capacities beyond 256GB or require UHS-II or UHS-III bus speeds for even higher throughput should look at other options.

UHS-I bus with V30 sustained write

The single specification that decides fit is the UHS-I bus combined with a V30 video speed class, guaranteeing a minimum sustained write of 30MB/s. This ensures the card can keep up with 5.3K and 4K UHD recording without dropped frames. Verify that your host device supports UHS-I to achieve the rated transfer speeds.

商品問答

What device slot does the 256GB microSD card fit into?

The card fits any microSDXC slot that supports UHS-I, including action cameras, drones, Android phones, laptops and handheld gaming consoles.

How is the card installed, and what step is often missed?

Insert the card label-side up until it clicks, then format it in the device settings before first use to enable the A2 app-performance rating.

When should the card be replaced to avoid data loss?

Replace the card if write speeds drop well below 170MB/s, if the device reports read errors, or after several years of heavy 5.3K video recording.
