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

I’ll be honest, I usually stick with the well-known memory card brands, but I decided to give this Think Assemble Basics 256 GB MicroSD a try — and I’m really glad I did. It’s been fast, reliable, and handled 4K video and large file transfers without any issues at all.The read and write speeds are right up there with the branded options I’ve used before, and it hasn’t given me a single error so far. For the price, it’s a real bargain.Honestly, I was surprised by how solid it feels and how consistent the performance has been. Think Assemble’s done a great job with this one — it’s a budget option that doesn’t feel budget at all.

It’s a memory card, it’s very reasonably priced and it does the job. Write times are (to my mind), very good. Not much else to say, really. Except. Recommended.

I purchased this Think Assemble 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 StorageWith 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 PerformanceRead 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 IncludedThe 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 TrustworthyIt’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. Think Assemble 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 is probably the fastest, best value 1TB microSD on the market currently. For a non express microSD card you’ll not find any faster speeds then those delivered with this card, however it is suitable for most usecases.I use mine in my Xbox Ally and run various games off the microSD itself including larger games such as GTA V, Star Wars Battlefront 2 Skyrim. I’d not recommend running the newest 2025 AAA games off it but older games run with no issues at good speeds.

It was recognized instantly, installed without any issues, and provided plenty of extra storage for apps, games, movies, and offline content.The performance has been excellent — apps load quickly, videos play smoothly, and there’s no lag at all. The A2 and U3 ratings really make a difference, especially for a kid’s tablet that gets used heavily every day.The included full-size adapter is a nice bonus, making it easy to transfer files from a computer if needed. For the price, the quality and reliability are outstanding.If you need extra storage for a Fire tablet or any device that supports microSD, this card is a great value and I would absolutely buy it again. Highly recommended!
