128GB Superior Micro SDXC UHS-I (U3), V30 4K A2, High Speed MicroSD Card with Adapter

Good

Great card. Using for outdoor camera. Works perfectly.

They work great for video.

I bought the Silicon Power 128GB microSDXC card expecting that might have low performance or might be even fake at this price range—but running Fake Device Test proved otherwise: Average Write Speed: 39.32 MB/s Average Verify Speed: 85.38 MB/s No errors during full 124.36 GB write-and-verify sequence That tells me this card is legit, not fake. Is it hitting the advertised 80 MB/s write? No—not in my test—but the discrepancy likely reflects file handling and real-world usage rather than a counterfeit product. On my Galaxy Tab S9, video playback is smooth, apps run flawlessly, and no glitches or slowdowns so far. I'm completely satisfied with its reliability and performance in everyday use. And lets not forget that read speed is pretty close to 100MB/s. ✅ Why I like it: real-world stability, zero verification errors, works flawlessly with my galaxy Tab S9. 🔄 Room for improvement: Write speed below spec—but still enough for 4K video and app storage. Overall: a genuine, affordable, and trustworthy card for media and tablet use. ⭐ 4 Other Great Options at This Price Range But in case you want more options to choose, Here are four solid alternatives worth considering: 1. Amazon Basics Micro SDXC (A2 U3, up to 100 MB/s) A budget-friendly and highly reliable card—with IPX6 water/shock/X-ray resistance and broad compatibility.
