Customer Ratings & Reviews

This is exactly what I was looking for my Go Pro Hero 4. The footage looks amazing and it downloads in seconds. Best memory card I ever purchased.

This memory card writes very fast. Is great to use with a GoPro that needs a high speed memory card. It allows you to record auto racing with out any lags in recording.

records and transfers at very high speed with great quality.

Performs well shooting with my GoPro 4. A must for shooting 4K.

I got this card for my DJI Phantom 3 and it worked great!

Holds tons of your data seamlessly. Large files not a problem

This is the awsome, the bomb I say buy this !!!!!!

I bought this card for my Nokia Lumia 1520. I needed a card that supports 4K recording. I have used lower end Sandisk cards and they were just not up to the task. After strenuous usage they would drop out and sometimes lose data. I also tried a Samsung Pro microSD and it was a fast. inexpensive card but would drop out temporarily with strenuous usage. I put this SanDisk card through it's paces by doing a full restore of the data on my phone which if I remember correctly was about 23GB. It ran overnight and usually other restores take several attempts and require a reboot to get the card back and this one did not drop out once. During the restore, the area of the phone where the card is installed got very warm but it never dropped out. That is no small feat in microSD. If I had one possible gripe, I would say I believe the card might have a higher latency than some other slower cards. It's a common issue that when you increase max throughput that you increase random access times. I don't store any critical apps on the card for reliability but comparing it to my Samsung Pro card it seems to take a little longer to do things that require accessing a small amount of data quickly. I haven't benchmarked it but rather just did a side by side comparison with an identical 1520. The phone with Samsung card shows all apps available quicker. Also, with 4K recording there is a stutter when starting the video that goes away after about the first 2-3 seconds. The Samsung card doesn't seem to have that stutter at the beginning but still does show one at random intervals. Once the Sandisk card gets a continuous stream of video pushed to it, it seems to stabilize and work great. Without further testing, I can't say if it is a card issue related to random access speeds or maybe a glitch in the Lumia Denim update. In the end, it is a minor gripe in an otherwise very stable card that performs consistently. My score is based on a comparison to other high speed cards I have owned so I did not take away a star for the possible random access times. I also rated it on the fact that with some careful checking and Best Buy's price match guarantee, this card can be purchased for a much better price.

did a few transfer tests and was able to sustain the rated write speeds. very fast card. upgrading 32gb extreme to 64gb extreme pro to use in gopro. hoping to help out video quality, read that slower cards can drop frames. we'll see. and an fyi about the pricematch, make sure the model number matches or don't waste your time. some online retailers advertise the g46a model, but you'll need to find one advertising the a46a. there is one on their approved list of online retailers that does, just not the most popular retailer. so search em all. you'll see.

i order this for my Dji Phantom 3 work perfect . if price too high price match other store just like me.
