SanDisk Extreme 64 GB microSDXC Memory Card + SD Adapter with A2 App Performance + Rescue Pro Deluxe, Up to 160 MB/s, Class 10, UHS-I, U3, V30, Red/Gold

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.

The SanDisk Extreme 128 GB microSDXC Memory Card with A2 App Performance and SD Adapter is a top-notch storage solution that excels in both capacity and performance. I bought this memory card specifically for my 4K drone video needs, and I am delighted with its outstanding performance. Capacity and Speed: The 128 GB capacity offers ample space to store large files, including high-resolution videos, photos, and other media. The A2 App Performance rating ensures smooth and rapid app loading and performance, which is particularly valuable for running apps and games directly from the memory card on supported devices. Performance in 4K Drone Video: When it comes to recording 4K drone videos, this memory card performs exceptionally well. The fast read and write speeds allow for seamless video capture, preventing any frame drops or glitches during recording. Additionally, the V30 video speed class guarantees a minimum sustained write speed of 30MB/s, ensuring smooth and reliable 4K video recording. Durability and Adaptability: The memory card is designed to withstand extreme conditions, making it resistant to water, shock, temperature fluctuations, and even X-rays. This durability is crucial for outdoor activities, such as drone flights, where the card might encounter various environmental challenges. SD Adapter: The included SD adapter is a valuable addition, allowing me to use the microSDXC card with other devices that support standard SD cards. It's convenient for transferring files to and from my computer or using the card with different devices. Overall, the SanDisk Extreme 128 GB microSDXC Memory Card is an exceptional choice for anyone in need of high-capacity, high-performance storage, particularly for 4K drone video recording. Its reliability, speed, and durability have proven to be essential assets during my drone flights, providing a seamless recording experience without any data-related concerns. If you're seeking a reliable and high-quality memory card for demanding tasks like 4K video recording, the SanDisk Extreme series is undoubtedly a great investment.

The number of devices that MicroSD cards work with now has increased demand, which in turn has really brought the price down of these fantastic cards. I don't use any other brand now that I know I can rely on SanDisk (having previously used them for several years without a fail in a dashcam and tablets). On top of being ultra reliable, they come with A2 App performance. You may think A2 isn't as good as A1, but it actually means read and write speeds are at least doubled (usually more). This makes them ideal for recording video in a dashcam, CCTV camera or video doorbell that produces high definition video at a high frame rate (does footage look laggy if movement is fast?) It comes with a microSD to SD adapter so that the card can be plugged directly into a card reader or laptop. It also comes with recovery software but I have never had to use it in the past and don't expect to in the future either. I will continue to trust in and spend my money on SanDisk and recommend that you do the same. You will not be disappointed. If you found my review helpful, please remember to let me know.

So I started by doing a check to make sure it was a 128GB card and not a smaller one mislabelled. (I simply copied a 126GB file to it and compared the hash of that with the original, using HashCalc.) This passed just fine, but I was disappointed that the write speed, for sequential writes to a brand-new card, was only 27MB/s using the supplied micro-SD-to-SD converter. This seemed odd, so I deleted the supplied partition (which didn't use quite all of the card), made a new one in the Windows-10 Disk Manager and formatted it as exFAT, which gave me a teeny bit more space. After this I got 80MB/s writes. So, the card seems okay, the format as supplied not so much. But maybe something odd was going on? I'd say test yours and if it's slow kill the partition, make a new simple one and format it as exFAT then see how it goes. Oh and the packaging is, as ever for micro-SD cards, a right pain to get into...

Nice and fast micro SDXC SD card. I use both in my mobile phone, Samsung tablet and mirrorless camera for the transfer of photos, both jpeg and dng, and music, plus it comes with a SD card adapter that plugs into my laptop. What's not to like? Buy it!

A few weeks back I bought this 1TB microSD card during an Amazon 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 Amazon 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.
