    • this card holds literally everything
Capacity: 400GB
400gb sounds like overkill until you start loading games onto your switch and suddenly it fills right up faster than you'd think. this card has been running solid for over a year with zero issues whether i'm playing games or recording video. sandisk is just reliable and i've never had one fail on me so this was an easy buy. ... show more

    • Excellent Product
Capacity: 128GB
This is an excellent memory card that I got for the Switch. I was far less expensive than the factory one, it has more memory, it holds tons more data, it works well, doesn't lag and has been an excellent addition for the massive amount of games we have.

    • The Memory Card and the Moment!
Capacity: 128GB
Review Image by A. Hans
I have always been fond of photography, the art of capturing the fleeting and the eternal, the mundane and the sublime. But I also know the limitations of my camera, the storage space and the transfer speed, the risk of losing or corrupting my precious images. That is why I was delighted to discover this memory card, which not only stores my photos and videos, but also transfers them quickly and safely. This memory card is unlike any other I have tried before. It has a large capacity of 128GB, which allows me to store even more hours of Full HD video. It has a fast transfer speed of up to 120MB/s, which lets me move up to 1000 photos in a minute. It is also compatible with Android smartphones and tablets, and MIL cameras, so I can use it with different devices. But what I love most about this memory card is its A1-rated performance, which makes it load apps faster and smoother. It is also engineered with proprietary technology to reach speeds beyond UHS-I 104MB/s, which means it can handle high-resolution and 4K videos with ease. It is suitable for all kinds of photography, whether it is landscape, portrait, or action. This memory card is more than just a storage device. It is a memory card for the moment. It makes me feel confident and creative in my photography. It allows me to capture the beauty and wonder of life, without fear or hassle. It is a reminder of the power and joy of art. I highly recommend this memory card to anyone of my friends who loves photography, but also cares about their camera. It is a must-have for every photographer and videographer. It is a memory card that will make you smile. ... show more
