Amazon Basics microSDXC Memory Card with Full Size Adapter, A2, U3, Read Speed up to 100 MB/s, 512GB, Black

Picked this up to use in a dash cam and it's been working perfectly. The 128GB capacity is plenty for continuous loop recording, and the A2 speed class means it writes fast enough that there are no gaps in footage. I also tested it in our Nikon camera as overflow storage when the main card fills up and the read/write speeds were more than acceptable for photos. The full size adapter that comes with it is handy too, saves buying one separately. Transfer speeds to the PC are quick, I was getting around 90MB/s reading which is close enough to the claimed 100MB/s. For the price compared to SanDisk or Samsung equivalents, this is a solid option. It's been in the dash cam for several months now through summer heat and winter cold and hasn't skipped a beat. The only reason I wouldn't use it as a primary camera card for professional work is that I'd want a higher endurance rated card for that, but for general use, dash cams, tablets and phones it's absolutely fine.

I purchased this Amazon Basics 128GB Micro SDXC memory card specifically for my child’s bedroom security camera, and it’s been absolutely perfect for the job. 💾 Plenty of Storage With 128GB, it can hold days’ worth of video footage without needing to constantly format or transfer files. It’s ideal for continuous loop recording and works seamlessly with our Wi-Fi-enabled indoor camera. 🚀 Fast & Reliable Performance Read speeds up to 100 MB/s are no joke! Transferring footage to my computer is quick and smooth—no freezing or lagging. Rated A2 and U3, so it’s fast enough for higher-demand uses too, like 4K video or mobile apps if needed. 🔌 Full-Size Adapter Included The included full-size SD adapter is really handy—I’ve used it to plug directly into my laptop’s SD slot for easy access to footage. No extra gear needed. 🔒 Durable and Trustworthy It’s been running non-stop in the camera for weeks with no errors. No corrupt files, no disconnections. It just works. Exactly what you need when it’s monitoring your child’s space. ✅ Final Thoughts: For the price, you honestly can’t go wrong. Amazon Basics has knocked it out of the park with this memory card—solid quality, great speed, and totally dependable. Whether it’s for cameras, phones, or other gadgets, this card is a fantastic choice. I’d definitely buy another for other devices in our home.

This micro SD card offers good speed and enough storage for my phone and camera — I’ve used it to store photos and videos and so far it works reliably. It’s nice that the full-size adapter is included, so I can use it with different devices. The only downside: the read speed isn’t always hitting the “up to 100 MB/s” — sometimes transfers are slower, especially when moving many files at once. Still, for everyday use it’s a solid card

This Amazon Basics micro SDXC card offers impressive read speeds up to 100 MB/s and performs reliably for storing photos, videos, and apps. The included full size adapter makes it easy to use with a variety of devices. It feels well made and durable, and the A2 and U3 ratings ensure smooth performance for high-demand applications. Overall, it is a solid, dependable memory card at a good value.

Perfect quality and value. Perfect for extra storage for my CCTV

I was surprised as to how fast this cards write speed was. Works flawlessly in my Fiio M21. I managed to fill 128 GB card up with my music files in 35 minutes. For an A2 card it represents excellent value for money.

Works perfectly with tapo tp-link cameras, which are very picky to using SDXC cards. A good alternative to the usual brands. Buy this high speed over the regular speed.

Great Product!

Producto funcional al cien por cien. Lee y escribe al instante, sin errores. Permite todas las funciones como si el archivo estuviera en el almacenamiento del móvil. Lee video o documentos a la perfeccion. Para los móviles actuales sin puerto para tarjeta SD me parece una compra esencial si piensas usar almacenamiento fuera del móvil aparte de la nube o para leer SD antiguas. Exporta grandes cantidades de datos en segundos y no ha dado ningún error de compatibilidad hasta ahora. Conexión sencillísima simplemente metiéndolo en la entrada usbc del móvil, sin cables ni adaptadores como otros.

Ok

Chegou em otimas condições, não tive como testar muito mas consegui saber que funciona.

Fast micro sd card. Uses for video surveyance.

Excelente tarjeta a un precio ajustadísimo en comparación con otras marcas que no ofrecen las velocidades que ésta sí consigue. Velocidades de transferencia, tanto en lectura como en escritura alrededor de 200 Mb/s.
