Review: Fast, durable, app-ready microSD. Great for 4K, Android, Switch. Needs good reader. - This card is built for high-speed mobile storage and 4K video capture. The A2 rating means it’s optimised for app loading and multitasking on Android devices—ideal for tablets, phones, and even handheld consoles. In benchmark tests, it hit 169 MB/s read and 103 MB/s write speeds using SanDisk’s MobileMate USB 3.0 reader1 . Other readers showed lower speeds (around 99 MB/s read, 87 MB/s write), so pairing it with a good reader matters. The V30 rating guarantees 30 MB/s sustained write speed, making it reliable for 4K UHD recording on action cams, drones, and mirrorless cameras. The included SD adapter makes it easy to slot into laptops or DSLRs. ✅ Pros Fast read/write speeds—great for 4K video and app-heavy devices A2 app performance—smooth multitasking and fast app launches Wide compatibility—Android, GoPro, Nintendo Switch, DSLR Includes SD adapter—easy transfer to PC or camera RescuePRO software—recover deleted files if needed Durable build—shockproof, waterproof, X-ray proof ⚠️ Cons Max speed only with SanDisk reader—other readers may bottleneck performance1 No hard case included—just retail packaging Price fluctuates—watch for deals Not UHS-II—still solid, but not top-tier for pro cameras Recovery software is time-limited—requires activation 🧍‍♂️ Personal Verdict Used this in a GoPro and Android phone—loaded apps fast, handled 4K footage without stutter, and transferred files quickly to PC. For under £25, it’s a proper upgrade if you want speed, reliability, and flexibility across devices.
Review: A little pricey but if you can spare the cash, it's fantastic to have so much storage on the move - A few weeks back I bought this 1TB microSD card during an desertcart flash-sale for about £330 to use in my Android smartphone, a 2018 HTC U12+. I liked the idea of having all my CD/Hi-res (FLAC) format music in my pocket on the move. I was also bored of having to convert down new music to MP3 format in order to accommodate my previous SanDisk 256GB microSD, which had put in a very respectable 5 year service by this point. The 1TB microSD was simple and efficient to use from the moment I inserted it into my phone. Android encryption enabled from the word go and it took about 15 hours to copy 800GB via the phone over a USB 3.0 connection. I simply left it going overnight and now have my lossless music collection in my pocket as intended, with bags of room to spare for future albums. Admittedly, £300+ is a lot of money and I ummed and ahhed about purchasing it for a good couple of weeks before taking the plunge. Value for money? Questionable. But the product itself is certainly of high quality and performed exactly to expectations so I can't fault those aspects. A Note on Counterfeit SanDisk microSDs: Thanks to an unscrupulous eBay seller I had been stung by purchasing a very convincing fake version of this card a few weeks before this desertcart genuine purchase. What did I learn? Stick to reputable sellers and if the price is too good to be true then it usually is. The counterfeit card became useless as once I began filling it with data, the "earlier" files I had copied vanished. There were other tell-tale signs including subtle differences in the packaging vs genuine (Made in Taiwan vs China) and there was no microchip "bump" on the back of the fake. A final thing to look out for is a genuine SanDisk microSDs should show up as "SanDisk SD card" in your device. If you've got a fake it will simply show up as "SD card", which is what I had. Thankfully I got my money back through the eBay/PayPal framework but it is wise to triple check images and listings when buying SanDisk microSDs.

### ⭐⭐⭐⭐⭐ Worth to buy!!
*by S***A on 3 June 2025*

Great. Bought for my dashcam after previous disappointment with different brand. This one is compatible, easy to format, just read Google suggestions and you can do all yourself. Came with little reading device, if your laptop is suitable for, then it's great advantage. Fit perfectly in camera, seems sturdy enough to not break or scratch easily. After formatting I drove around in the night and then I checked all videos are clear to see and recorded. Happy with video recording, now I don't have to be worried as I was before just in case of accident. Thank you
