Fast micro SD card. And by fast, I mean ULTRA fast. This thing has faster read and write speeds than most SD cards in its class from different brands such as Sony and Samsung. I've used this micro SD card for devices such as action cameras and handheld portable gaming devices. 128GB is a lot of space all in this little guy. Data transfer speeds also make it convenient to share and archive your files quickly and efficiently. I would recommend this to anyone who needs a micro SD card. I have always trusted SanDisk memory cards and this one is no exception.

There is an adapter that is also included for the memory slots that require the bigger version. This is a useful bonus item to carry around in your accessory kit. You never know when you'll need to transfer files to a device that only takes SD cards yet this is a mini SD card. The dollar price per GB of capacity has gone down drastically in this card. I remember when it used to be $17 for 32GB. I like how it's at about $11 now yet the speeds are still there. And that's essentially what makes this card one of the most selling cards out there.

This card tested at 88MB/s read, so it meets its claim. The 4K speeds are fairly slow at 5MB/s and the sequential write is 15.8 MB/s which should suffice for most applications. This will work well for most people's needs. Tests done on a Kingston FCR-HS3 USB 3.0 reader using CrystalDiskMark 3.0.3 x64.


Personally, I've used this 128GB micro SD card for my new Amazon Fire HD 10, 10.1" HD Display, Wi-Fi, 16 GB. I knew that I'd want plenty of space, since I'd be using it a lot for downloading music, photos, and movies. This is a must have if you deals with anything that requires an SD card and you'd like plenty of storage!

This SD card has also been tested with use for the Gopro Hero 2.
