Q: Is this compatible with the Sony Alpha 7CR mirrorless camera?
A: Hi, thank you for reaching out to us. The SanDisk Extreme PLUS microSDXC UHS‑I card can be used with the Sony Alpha 7CR—but only with a suitable SD adapter what we do not recommend, as it won't operate at full speed. The camera’s slot is designed for full-size SD cards (SDHC/SDXC) compatible with UHS-I or UHS-II standards. If you want optimal performance, go for a full-size SDXC UHS-II card like the SanDisk Extreme PRO.
Q: Does this work with the Switch 2? Will it work well with the Switch 2?
A: Hi, thank you for contacting us. Unfortunately, it will not work correctly with the Nintendo Switch 2. The Nintendo Switch 2 is compatible with SanDisk microSD Express cards (marked with an “EX” symbol) for game storage. Your card is a UHS-I type, which doesn’t meet the Express specification.

Optimized for mobile gaming, the 256GB Extreme UHS-I microSDXC Memory Card from SanDisk features a storage capacity of 256GB and supports maximum read speeds of up to190 MB/s and maximum write speeds of up to 130 MB/s. This card has also been designed with the V30 Video Speed Class rating, which guarantees minimum write speeds of at least 30 MB/s. All of this allows for users to immerse themselves in AAA, 3D, and VR gaming, as well as extreme sports videography and photography at resolutions of Ultra HD 4K (3840 x 2160) and Full HD (1920 x 1080). While this card has been designed for cameras that are UHS-I / V30 compatible, it may be used in devices that do not support UHS-I / V30. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-I and U3, which also support minimum write speeds of 30 MB/s, UHS-I and U1, which support 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 able to withstand temperatures from -13 to 185°F, allowing you to take this card with you into extreme environments, such as snow and deserts. Protection is provided by a limited lifetime warranty.
