SanDisk Extreme 32 GB microSDHC Memory Card + SD Adapter with A1 App Performance + Rescue Pro Deluxe, Up to 100 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.

I bought two of these to use in wifi cameras at a construction site, and they’ve been running 24/7 for over three months now with no issues. The footage is 2K and the cards handle the looping video perfectly with no glitches, break-ups, or corrupted files so far. Setup was very simple. The cameras auto-formatted the cards and were ready to go right away. I haven’t had to use the SD adapter or the included software, but it’s nice to have them included just in case. The cards have also stood up well to challenging site conditions. There was damp, later dust, and direct sunlight. No signs of failure or degradation yet. I use these cards on the cameras' local storage option (not the cloud storage), which saves money. I’m very happy with the performance and reliability so far. I have attached a video to illustrate the video quality downloaded from the device - there were no glitches or quality issues.

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!

Works good. Disappointed in the brand. Just seen the black friday sales. I bought this at normal price for £108. According to black friday sales this is 67% off and £97!!! Wtf Sandisk! hike the price by 300% to around £280 just before black friday to create a pretend sale! DO NOT FALL FOR THE MARKETING PEOPLE. Its a good card but the price is not as good as it seems

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

Bought for my 3ds, no issues from sandisk. Works perfectly

Does what it says, 32gb was the max size I could use for one of my devices and this does the job perfectly from a reputable brand. Price was extremely good as I picked this up in a sale, but either way it's still a good price for the product.
