SanDisk Extreme PRO 64 GB microSDXC UHS-I Memory Card

After purchasing a Lexar 633X 32GB and wondering why it wouldn't work in my Sony FDR-X1000V even when I had it in 1080p 24fps 50M recording mode, I took no more chances and went straight for this one. The camera responds much faster, doesn't delay once turned on anymore and allows me to record in the max 4K 30fps 100M mode. This card is brilliant, and the best you can get for this price!

Fantastic product. I was having problems with the SD card I received as part of a package with my Go Pro Hero 4. If I filmed for over 2 mins it would come up as 'SD Error' and I couldn't watch my play back.Searched for solution on Internet and a blogger recommended this card. It was cheaper than expected and it has solved all the issues I was having.Highly recommended. Quick delivery too.

This is not the cheapest of SD cards but as the saying goes 'you get what you pay for'...I use this card for my Phantom 3 Drone and is absolutely perfectly. The speed, capacity and general quality is outstanding. Would highly recommend.

Out of the box this card was a PIA to set up for me. It appeared as a 1mb logical partition and My windows 7 build pc was incapable of formatting it correctly without additional software. My intentions were to format in FAT32 for my Nintendo 3DS and so I had to use 3rd party tools to do this. Aside from the initial faff this micro sd card seems fast, though I haven't done any formal benchmarking. I'm almost tempted to get another for my camera. I'd wager most new devices such as mobile phones will auto format this card anyway so don't be put off by my experience. I've had good experiences with SanDisk memory cards in the past and very few corruptions - I will update this review in a couple of months to see if it holds up to the brand reputation.

I got this almost 10 months ago after some video and photos were saving incorrectly when using the GoPro Hero 3, and corrupting the files. This has fixed the problem and all video and photography are saving great. It works great with long and short video recordings and when stopping and starting within seconds of each other.This card should be shipped with the GoPro as it has fixed all recording issues I have had when using other memory cards.

Good price and excellent quality. You need this top of the line one for rigorous use and it's not slow like the others.

Great - capacious and fast. We use it in the GoPro and have been very pleased with it. A bit expensive, but you pay for speed . . . .

This micro card works as expected. Is fast when linking into my MacBook Pro through the GoPro unit via USB. Data transfer is quick and the 64gb gives a full 4hours @ 4K resolution (longer than the battery lasts). Only reason that I have not given 5 stars is due to price. The prices soon will fall as memory and speed increases, but for my Hero 4, 64gb is the largest San Disk card it will take.
