Quadruple the storage of my first computer

[This review was collected as part of a promotion.] It's kind of insane that this tiny fingernail sized card is not only faster but holds about 4 times the capacity of my first computers entire hard drive!
This little card worked great in our 360 camera and gopro, even after being knocked over by a volleyball more than once!
It's much faster than our old card and holds twice the amount of footage for when we procrastinate pulling the files down.
Speed wise, this card made short work of three days with of tournament footage!
I would recommend this to a friend!

Super fast!

[This review was collected as part of a promotion.] My hubby is the primary techie. I must say, after using it, that this is VERY fast memory and blows the older memory out of the water. We have used it in cameras and phones and it is great. for writing videos and photos.
Writes quickly and no lags when writing. Great storage space.
I am glad he got it to try and we will probably buy more of this memory in the future.
