Price is great when it's on sale plenty of stock available when I purchase in store

speed is regular speed, if you need fast read/ write speed for action cameras, may need to look for higher speed card

At special price, it doesn't hurt to grab one or even two as spare. They can be handy when you need it. 1 card at regular price = 4 cards at special price,

Awful product - glitchy and inconsistent until it stops working all together and takes your data with.

Not sure why Memex persists in carrying this blighted line, hopefully all the crap reviews will eventually make them reconsider.

The word "Premier" makes it sound superior

2yrs, it failed..

Had this in my Samsung Galaxy S8 when it first came out, lasted up until this year March 2019. Wiped out 2 yrs worth of photos and videos of my kids... Luckily, I'm an IT super nerd and had my phone backed up on 2 seperate clouds, Google and Samsung.

Worthless

I warn you from buying anything from this brand called Adata unless you want to loss all of your data stored on it after maybe 3 months. I have tried 2 different models of thier sd card 32gb and 128gb and both endup failing after few months and losing all data was stored along the way

Dependable so far.

Formatted exFAT (like most >32GB cards).

Bought to use in a Raspberry Pi2 model B. Had to be reformatted from exFAT to FAT for the board to use "see" it, boot from it. Once formatted, has worked fine.

Speed of this monolithic mSD card write speed - 25 MB / SEC read speed - 90 MB/SEC works like regular USB 3.0 flash A-DATA This is good brand. we use a lot

good for cellphones and for video dash cam. Also possible use in camcorders.
