It is so hard to imagine that you can have 32 GB is something smaller than a postage stamp, yet here it is.I bought this card to work with my Call of Duty Ghosts Tactical Camera and it works perfectly.  The camera came with a 4 G card which I filled in just over an hour at the local Kart track.  I missed the last bit of our race due to insufficient capacity.  The battery was still going strong so I needed more card for recording my adventures.This card fits the bill nicely.As a UHS Speed Class 1 (roughly equiv Class 10) card this SD card is quite capable of any photographic or video need up to Full HD (not 2k or 4k).  I use a similar card in my Canon 60D and am able to hold around 700 raw images, and a few hours of HD video.Here are some benchmarks for comparison including this card.MacBook Pro Retina SSD430 MB/s write323 MB/s readGeneric Class 6 4GB (Came with Ghost Camera)9.8 MB/s write21 MB/s readSanDisk Extreme Class 10 8GB21 MB/s write23 MB/s readThis Card San Disk Ultra UHC 112 MB/s write45 MB/s readWhat does this mean?  It means that you should have no trouble recording HD video reliably with this card.  Your camera will be able to save pictures quickly to this card so it is ready to take the next shot.  If you fill the card completely it will take roughly 12 minutes to copy all the data off of the card, assuming the device you are copying to can keep up.The tests were done in the built in SD card drive of the MacBook Pro using the included SD Card Adapter.Based on my tests, I would say that if you don't really need a Micro SD, then you should buy a standard SD card, your performance might be better and the price should be lower.  However, if you think you need or might need a Micro SD down the road, this is a suitable solution.
