I’m using the Amazon Basics MicroSDXC UHS-I Class 10 (64GB, 2-pack) for desktop file storage and backups, and they work flawlessly. The included full-size SD adapters make it super convenient to plug into my desktop's SD card reader without needing an extra dongle or USB adapter. Read and write speeds are fast—perfect for transferring documents, photos, and even larger media files. I’ve used them for everything from everyday work backups to storing PowerPoint presentations and PDFs for travel, and they haven’t let me down. They mount instantly on my desktop, and I’ve had zero issues with data loss or corrupted files. Reliable, fast, and affordable—perfect for organizing digital clutter or transporting files between machines. Highly recommend for anyone needing a simple storage solution for desktop use!

works great. I got it for my 5-year-old to put in her camera, and the quality is great. Super easy to install, of course, and it's fast too. Thank you!

Why did you pick this product vs others?: After using the Amazon Basics 64GB MicroSDXC cards for my GoPro Hero 9 over the past three months, I've been thoroughly impressed with their consistent performance. The two-pack arrived in simple but secure packaging, and each card came with a full-size adapter that's proven handy when transferring files to my laptop. What first caught my attention was the A2 and U3 ratings, which promised fast app performance and 4K video capability - specs that initially made me skeptical given the affordable price. Recording 4K footage at 60fps has become my standard practice with these cards, and they've handled it without a single dropped frame or overheating warning. I regularly shoot hour-long sessions while snorkeling, and the cards maintain steady write speeds even when the camera gets warm in direct sunlight. The claimed 100MB/s read speed feels accurate when I'm transferring files to my computer - a 30GB dive session transfers in about 5 minutes, which is significantly faster than the generic cards I used previously. Memory quality: What surprised me most was how well these cards perform with the GoPro's advanced features. Timewarp videos, 240fps slow motion, and HERO mode photos all save instantly without any lag or buffering. I've filled these cards completely multiple times during road trips, and they've never corrupted files or failed to save important moments, which happened occasionally with my old cards. The included adapters work perfectly in my DSLR too, making them versatile for all my photography needs. Durability has been excellent despite heavy use in various environments. After being submerged in saltwater, exposed to desert heat, and frozen during winter hikes (accidentally left in my jacket pocket), both cards still function flawlessly. The black finish shows no signs of wear, and the locking mechanism on the adapters remains firm after dozens of swaps between devices. I appreciate that they maintain consistent performance even when nearly full - some cards slow down significantly when storage space gets low. Reliability: For the price of this two-pack, the value is outstanding. I've tested these side-by-side with name brand cards that cost twice as much, and the Amazon Basics cards match them in real-world performance. Having two identical cards means I always have a backup ready when one is transferring files, and the peace of mind knowing both are reliable is worth the purchase alone. They've become my default recommendation for fellow action camera enthusiasts. After recording over 500GB of footage across multiple adventures, I can confidently say these microSD cards outperform their price point. The combination of speed, reliability, and included adapters makes them ideal for anyone needing dependable storage for 4K video. They've handled everything from professional shoots to family vacations without fail, proving you don't need to spend a fortune for quality memory cards that keep up with demanding cameras.

I use this micro SD card with my Eufy doorbell video system. It works without any problems and has reasonable read time. Excellent price for its capacity. It also comes with an adapter for non micro slots.

Installed this in my Tapo security cam, and it’s been running like a champ. Continuous recording, playback, and motion clips all work smoothly, and I don’t have to babysit it. It handles the loop recording without stuttering, which is all I really care about for home security. For the price, it’s unbeatable. No need to overspend on a “fancy” branded card when this does exactly what you need. If you’re running Tapo or similar cams, this is an easy, affordable choice that just works.

This card delivers good read/write speeds for the price—great for Full HD and 4K video recording. The 256GB capacity is accurate and works well with phones, tablets, cameras, and even Nintendo Switch. It comes pre-formatted as exFAT, so it’s ready for large files. I tested it and the storage is genuine, not a knockoff. Took off one star because it’s not quite as fast as premium brands, but for everyday use, it’s a great value.

This worked perfectly for my son’s tablet! He’s always downloading games and apps, so he used to run out of space constantly and we’d have to delete things. Now with this 128GB card, he has plenty of storage for everything he wants. It was super easy to install and worked right away. The price was great, shipping was fast, and I’ll definitely be buying another one when we need more storage for our other devices.
