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!

[This review was collected as part of a promotion.] The compatibility is the #1 feature i love about this product with my phone. The capacity is the second feature that wins me over although it depends on what your needed the memory card for really. The durability of the product is just fine, no problems there. The reliability couldn't get any better. I have always been able to rely on it reliability. The speed is great depending on what your needing it for. There are different speeds for different reasons. Great features all around.
I would recommend this to a friend!

Noticeable Speed Bump
on June 11, 2026
Posted by: Anonymous
from Houston
[This review was collected as part of a promotion.] I was worried that I was not going to be able to notice the difference between this microSDXC card and my previous one but I was pleasantly surprised. I have lots of cameras around my house that allow the use of a microSDXC card, and when reviewing recorded footage on previous cards from my phone, it always took a bit of time for it to load. Not a crazy amount of time, but enough to where you start to wonder if there is something BETTER out there than can speed up the process. Then I started to use this SD card. Reviewing footage is now smoother and faster than ever.
I would recommend this to a friend!
