    • Great SD card brand

This SD card worked great for modding my wii. The data storage worked great and reads just fine. It was perfect for that project. Well worth the price!

    • Good
Style: Memory Card Only Capacity: 128GB

    • Reliable SD Card — Fast, Easy to Use, and Great Storage!

This SD card is exactly what I needed! It’s super easy to use — just pop it into your camera, phone, or other devices, and it works right away. I used mine mainly for storing photos, videos, and some files, and it handles everything smoothly. The speed is great — transferring photos and videos is fast with no lag or errors. I’ve even used it to record HD videos, and the files saved quickly with no issues. It’s perfect for both everyday use and bigger projects where you need reliable storage. What I really like is that the storage space is exactly as described, and it doesn’t slow down as it fills up. Some SD cards I've used before started glitching when they got close to full, but this one stays fast and stable. The card feels sturdy and well-made, and it comes in a small plastic case, which is really helpful for keeping it safe when I’m not using it. If you need a good, reliable SD card for photos, videos, or extra storage, this one is perfect. It’s fast, simple, and totally dependable. I would definitely buy another one! ... show more

    • Like a lot
Style: Memory Card Only Capacity: 32GB (3-Pack)
Super useful, it comes with a lot of them, and you can use them for cameras, still cameras, video cameras, and even SD cards on your computer. And it's best to have several in case they get damaged. Plus, they're very reasonably priced, in my opinion. Súper útil trae muchas y puedes usar para cámaras, para cámara de fotos, cámaras de video, para colocar en SD. en tu computadora. Y es mejor tener varias por si se dañan. Además tienen muy buen precio a mi parecer. ... show more

    • Reliable Performance for Everyday Photography and Video
Style: Memory Card Only Capacity: 128GB
I recently purchased the SanDisk 128GB Ultra SDXC UHS-I Memory Card for my DSLR camera, and it has been a solid performer for my photography and video needs. Storage Capacity: With 128GB of storage, I have ample space to capture thousands of photos or several hours of Full HD video. This capacity is ideal for extended shooting sessions without the need to swap cards frequently. Speed and Performance: The card offers read speeds up to 140MB/s, which facilitates quick file transfers to my computer. While the write speeds are sufficient for Full HD video recording, I would recommend considering higher-end cards for 4K video to ensure optimal performance. Compatibility: This SDXC card is compatible with a wide range of devices, including DSLR cameras, camcorders, and even some drones. It's a versatile choice for various shooting scenarios. Durability: SanDisk cards are known for their durability, and this model is no exception. It's designed to be waterproof, shockproof, x-ray proof, and temperature-proof, providing peace of mind during shoots in challenging conditions. Value: Considering its performance and reliability, the SanDisk 128GB Ultra SDXC UHS-I Memory Card offers excellent value for both amateur and enthusiast photographers and videographers. ... show more

    • Works as expected
Style: Memory Card Only Capacity: 32GB
Got what I ordered and on time. The Card packaging was a bear to open. No documentation to describe the formatting that the card had, "as is". However, I used it as received and it worked as expected, so assume that the formatting was FAT32.
