I bought this for my GoPro video camera. The battery failed a couple of times, but I never had to change memory cards once (I bought two of these). All videos and photos were taken using just one memory card. I must have taken about one hour of 1080p HD video, together with at least 500 photos.

While expandable storages continue to be the most demanded accessory in history, the need for higher storage space continues to grow at a fast pace. But who would have ever thought that it was possible to cram in over 200GB of data storage in something as small as the SanDisk 200GB Ultra MicroSDXC...

+ Fast transfers; + Fast write speeds; + 200GB massive storage; + Small form factor

Our Editors' Choice remains the SanDisk Extreme 64GB , which offers a great balance of price, reliability, and performance at 62 cents per GB, and will probably satisfy the broadest range of buyers. Like the faster Extreme Pro lineup, the 200GB card is destined to thrill a passionate niche.

Most capacious microSD card ever; Fast enough for 4K video

Expensive per gigabyte; Not fast compared with competition

Delivery service little bit slow everything else are fantastic. Good service

Do what it's expected ... and this fast. Good buy on campaign

It does what it says "on the tin" as it were, well priced.

This card is great. I would buy it again.

I bought this card after reading that benchmarked read and write speeds exceeded those of some of the Sandisk Extreme MicroSDXC cards yet it costs less; 80-100MB/s sequential read and write, Also, I had bought the A1-rated version of the Sandisk Ultra 128GB MicroSDXC card from another company,...

I'm currently using the card in a Samsung Galaxy NX Android-based camera which is effectively a Samsung Galaxy S3 or S4 phone and has similar limitations with regards to SDcard read and write speeds; So while I have been able to realize the 80-100MB/s read and write speeds as other benchmarks have...

I bought this a year ago and I have to replace it because it failed not a happy camper I lost a lot of photos and my music very ticked off shop around and read reviews on the product

Just a few years ago if you'd told me we'd be able to stuff 400GB of storage into something the size of my thumbnail, I'd have probably dismissed it as fantasy. After all, it wasn't that long ago when 8, 16 or even 32GB memory cards were more than sufficient. Such is the pace of technology.
