I picked this card up for my galaxy tab a. It works great! Lots of room and the 60mb/sec transfer rate is plenty fast for capturing or playing HD video.
Speed was very good (93 MB/s read, 66 MB/s write). I've owned two of these 64GB cards. The first one died, lost everything. The second one, also used in my phone, the phone said the card is bad, as it did with the first one. I stopped using the 2nd one before I lose everything again. I thought the phone was bad but I got two of the same phones brand new and tried with other brands of cards and they work flawlessly.
it was a great purchase, it is plenty size for storing 10+ HD movies. Speed is great, price is unmatched comparing to other stores. There is really nothing to complain, i will buy another soon.
I am using this micro SDHC card in my Samsung Galaxy Grand Prime smartphone. It is working great and I cannot discern any lag when taking photos or videos.
The shipment was fast and the micro SDHC is working just great with my Samsung Galaxy Grand Prime smartphone. I have not noticed any lag using the memory card.
It is half price at sears with this great 64G memory, the access speed is fast. Application loaded on the SD card has no noticeable performance downgrade comparing to loading from the phone memory, will buy another one.
