Works great!

Reviewed in the United States on June 7, 2024

This is ample storage space for our DJI drone or GoPro Hero 12. It is compatible for pretty much any camera set up I have. It doesn’t heat up and it’s easy to format.

Not much more to be said! It’s a great product and does the job for what we need. And it’s great value for the money!

Amazon Basics Micro SDXC: The Unsung Hero of Digital Storage

Reviewed in the United States on December 15, 2023

n a world obsessed with flashy brands and exorbitant price tags, the Amazon Basics Micro SDXC card stands tall as a shining beacon of value and performance. Don't let the "basic" moniker fool you, this little powerhouse is anything but. Here's why it's become my go-to storage solution for all things digital:

Speed Demon: Forget stuttering downloads and laggy apps. This card boasts blazing-fast read and write speeds that make transferring even the chunkiest files a breeze. My 4K videos load in seconds, and my phone feels like it's been injected with a shot of digital espresso.

Capacity King: Whether you're a photo-snapping shutterbug or a game-hoarding gamer, this card has your back. Available in a variety of sizes, from a generous 64GB to a monstrous 1TB, I haven't even come close to filling mine up. It's like a bottomless pit for all my digital treasures.

Reliability Rock: Worried about data loss or corruption? Don't be. This card is built to last, with rigorous testing and quality assurance ensuring your precious files are safe and sound. 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.

No Frills, All Thrills: Some might say it lacks the bells and whistles of its fancy counterparts. But who needs fancy labels when you have pure, unadulterated performance? This card does exactly what it's supposed to do, and it does it flawlessly. No gimmicks, no fuss, just pure storage satisfaction.

The Verdict: If you're looking for a reliable, high-performance, and insanely affordable SD card, look no further than the Amazon Basics Micro SDXC. It's exceeded my expectations in every way, and it's become my go-to recommendation for friends and family. Trust me, you won't be disappointed.

Rating: 5 out of 5 stars (and a big thumbs up for value!)

Two-pack with Full Size Adapter

Reviewed in the United States on June 5, 2024

Amazon Basics’ products are often somewhat less expensive than similar products. Not in this case: this two-pack cost just a bit more than other two-packs or buying two singles. But the carrying case and included (single) full size SD card adapter make up for that.
I bought this product because I’d ordered another brand’s “64GB” cards, but they really only had “64 billion” byte capacity. That’s not what I needed. The Amazon Basics Micro SD cards, on the other hand offer the full 64GB (binary) capacity.
They came formatted with either FAT32 or ExFAT (I can’t recall), but you can format them for whatever your application needs.
One thing I like about Amazon’s labeling is that the cards are black with clear, white lettering, making them easy to read and aesthetically pleasing.
These cards are rated at 100Mb/s, U3 and V30 class. I haven’t done any detailed testing, but they transfer data quickly enough for HD video at 30fps.
This package is a good choice and a good value.

Great Value for Money

Reviewed in the United States on April 28, 2024

I purchased the Amazon Basics Micro SDXC Memory Card for my GoPro camera, and I'm extremely satisfied with its performance.

The 128GB capacity is perfect for storing all my high-resolution photos and 4K videos. The read speed of up to 100MB/s ensures that I can transfer files quickly and efficiently.

I also appreciate the durability of this memory card. It's shockproof, waterproof, temperature-proof, X-ray-proof, and magnetic-proof, making it ideal for use in various environments.

The included SD adapter is a nice bonus, as it allows me to easily transfer files to my laptop or desktop computer.

Overall, I highly recommend the Amazon Basics Micro SDXC Memory Card to anyone looking for a reliable and affordable memory card for their devices.

It doesn't matter that it has an Amazon brand on it!

Reviewed in the United States on April 20, 2024

This is a true bargain for a memory card. I originally purchased this thinking that I would put it my phone. Way more memory than I need on my phone. I decided to use the memory card in my camera. This SD micro memory card came with an adapter that turns it into a standard-sized SD card that fits into other devices. Definitely a good value, and it works as it's meant to do. To me, It really doesn't matter what the brand name is so long as it's dependable. I would recommend this product as a "good buy.!"

Best value for the money

Reviewed in the United States on May 16, 2024

Like other Amazon Basics products, one may wonder what the catch is for the cheaper price tag. Is it quality? Definitely not! We bought the 64GB version of this memory card for our home surveillance cameras, needing to store and playback video at anytime. The cards come well-packaged in a cute little box with an SD card adapter if you need the compatibility. After reformatting, >99.5% of the expected storage is available for writing. Reading from the card works perfectly and we have no complaints. Other micro SD cards on the market do not have much to offer or differentiate itself, so for me, in the end it came down to price; and Amazon Basics gives you the most value for the price. I highly recommend!

Works good

Reviewed in the United States on May 4, 2024

Went through 5 cards before this one. None would work with my fire. This however works flawlessly. Have it set to expand storage and it is great. When the prices drop I will get a bigger one.

Great storage capacity for small price.

Reviewed in the United States on May 31, 2024

I was originally going to use this for an old Olympus camera that I Thrifted but unfortunately I was not able to make that work (that was on me not on this product). I didn’t wanna waste this product because I purchased it. I was trying to find a way to use it and then I remembered I had an Nintendo switch and then Nintendo storage cards are very expensive and I wasn’t willing to pay for that so I use this one. It works perfectly fine. I’m super happy with it and I haven’t had any issues
