## Product: Samsung EVO Select 128GB microSD Card
**Brand:** SAMSUNG

The Samsung EVO Select 128GB microSD card offers solid performance across a range of devices. According to the manufacturer's product description, it boasts read speeds of up to 160 MB/s, making it quite handy for capturing high-res photos and 4K UHD videos where speed really matters. 

The write speed is rated at U3, Class 10, and V30, indicating a minimum of 30 MB/s. This means it's good for things like action cameras and other applications that need fast writing speeds.

However, keep in mind that the actual performance might differ based on what device you use. Our research has shown some hiccups with the [Asus ROG Ally](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dasus%2Brog%2Bally%26tag%3Dssw.ans.tx-1-20) – the card sometimes isn't recognized regardless of the format or method you use to install it. 

It's typically reliable with gadgets like smartphones, tablets, and even the [Nintendo Switch](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dnintendo%2Bswitch%26tag%3Dssw.ans.tx-1-20), but the Asus ROG Ally seems to be a tough nut for it to crack.

So, if you're planning to use this card with the Asus ROG Ally specifically, you might want to explore other options or check out the device’s manual. It often lists memory cards that have been tested for compatibility, which can help you dodge any future hassles. 

Just a friendly reminder to double-check compatibility when buying a memory card for a certain device—sometimes quirks or limitations can pop up. 

Good luck with your shopping!
