    Needed a SD card for our new doorbell cam. This works perfectly and puts 128GB in a super small package for a good price. That was the highest SD card it took.

I’ve dropped it, soaked it, and even accidentally run it through the laundry, and it’s still kicking strong.

    Value Vanguard: Let’s talk about the real hero here: the price. This card offers incredible bang for your buck, putting those overpriced brand names to shame. You’re getting top-notch performance and durability without breaking the bank. My wallet sings its praises every time I pull it out.

This card does exactly what it’s supposed to do, and it does it flawlessly. No gimmicks, no fuss, just pure storage satisfaction.

    This is a great budget backup micorSD memory card for a trip to Costa Rica where I took a ton of photos and wanted secure copies to prevent loss or overloading of the camera cards. It works fine as a backup and a great price for almost a half a terrabyte of space. It was delivered very promptly after ordering in perfect condition in commercial packaging with an SD adapter.

    Es la primera vez que veo la marca de AmazonBasics en tarjetas SD, estaba escéptico pero el precio me convenció y afortunadamente la calidad lo vale. Uso esta tarjeta en mi cámara fotográfica y funciona a la perfección. No dudaría en usarla en mi smartphone, cámara de acción (GoPro) o para mi consola de videojuegos (Nintendo Switch). También podría servir para grabación de video en 4K, pero personalmente recomendaría invertir extra en una tarjeta SD de mayor velocidad de lectura/escritura para conseguir un desempeño óptimo. En conclusión: bueno, bonito y barato, cumple sin problemas para casi todos los escenarios.

    I’ve purchased other SD cards, directly from China, and sometimes they appear to be one size when you look at the “properties” but if you actually try copying to them, you find out they are MUCH smaller. But with THESE cards, I got the FULL advertised size.

    Also, with one of the cards, I put it in my home automation server (Home Assistant) which is constantly writing/reading to the card and the device has been performing perfectly for weeks now.

    Excellent value. I’ll be buying more of these!

    As an avid photographer and videographer, I’m always on the hunt for SD cards that provide ample storage space without slowing down my workflow. I decided to give these Amazon Basics microSD cards a try for expanding the capacity on my devices. Here’s my assessment after testing them out:


    – Great value for money. You get two 64GB cards for a very affordable price.
    – Fast 100MB/s read speeds allow quick transfer of large media files like 4K video. No lag time.
    – A2 and U3 ratings indicate they can handle intensive tasks like gaming or recordings.
    – Full-size adapter makes it easy to transfer files from the microSD cards to my laptop.


    – Write speeds are slower than read speeds, so saving files takes more time.
    – Durability seems questionable based on other reviews. May fail under extreme conditions.
    – Gets slightly warm during extended file transfers. Could impact longevity.
    – Brand is not as prestigious as SanDisk or Samsung. Reliability may be lower.

    Overall, for the low price these Amazon Basics microSD cards are a solid value. They provide ample space for photos and videos and allow quick file transfers to my computer. However, the slower write speeds, potential durability issues, and lack of a top-tier brand name prevent me from fully recommending them for professional use. Casual users on a tight budget will likely appreciate them. But photographers/videographers may want to spend a little more for peace of mind. Hope this review helped!

    Needed extra storage in tablets and these worked PERFECTLY! Easy to install and the OS picked right up on them. For the price, these are hard to beat in storage amount and cost! Highly recommend these!
