SanDisk 400GB UHS-I microSDXC Overview

Designed for microSD devices such as smartphones, interchangeable-lens cameras, drones, or GoPro action cameras that can capture Full HD, 3D, and 4K video, as well as raw and burst photography, the 400GB Extreme UHS-I microSDXC Memory Card from SanDisk has a capacity of 400GB, is compatible with the UHS-I bus, and features a speed class rating of V30, which guarantees minimum write speeds of 30 MB/s. If your device does not support the V30 standard, this card also supports the U3 standard, which also guarantees minimum write speeds of 30 MB/s. Read speeds are supported up to 160 MB/s and write speeds max out at 90 MB/s.

While this card has been designed for cameras that are UHS-I / V30 / U3 compatible, it may be used in devices that do not support UHS-I / V30 / U3. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-I and U1, which supports minimum write speeds of 10 MB/s, or Class 10, which also supports minimum write speeds of 10 MB/s.

Aside from support for UHS-I, V30, and U3, SanDisk also built this card with support for the Application Performance Class 2 (A2) spec, which includes optimizations to give Android users an improved mobile experience, delivering faster mobile app performance. The A2 spec allows the card to manage random read input-output access per second (IOPS) operations so it can quickly open apps and process accompanying tasks, such as audio, graphics, saved profiles, and in-app permissions.

As with most SanDisk media, this memory card is shockproof, X-ray proof, and waterproof, while also being able to withstand temperatures, allowing you to take this card with you into extreme environments. Should the card's data become compromised, you also benefit from the option to download RescuePRO Deluxe software, and SanDisk's Memory Zone app offers users a simple way to organize, browse, and back up files on their Android mobile device. Additionally, included is a microSD to SD adapter with a write protect switch, allowing this card to be used in SD-compatible devices.

The fastest microSD card

By Ming

It's small and fast. No other microSD card's speed comes closer to this one. However, I don't like Sandisk color. Red and brown together is not a nice looking.

Big storage in a little card

Great secondary card for dual card slot cameras. I put this in the second slot of my new Canon R6 that i ordered from B&H and I have the second card slot programmed to capture JPGs as a backup to my first card slot. It's a great insurance policy in the event that you ever have any kind of issue with your primary images.

Excellent product !

will this card work in GoPro Hero7?
Asked by: Douglas
The latest GoPro 7 Black manual states that the card can be a capacity up to 256GB. This 400gb card would most likely be too large. Firmware updates possibly may change the capacity in the future.

That information is in the user's manual (available online), most likely in a table in the "specifications" section, most likely in the back of the manual. No matter where you get it from, the specific answer will depend on your choice of frame rate and resolution.
