Patriot 128GB A1 / V30 Micro SD Card for Android Phones and Tablets, 4K Video Recording - 2 Pack Retail Units

Capacity and quickness in read/write.

The description stated for use with 4K video with reading speed unto 100MB/s, write speed unto 80MB/s. But on the back of the package it said write speed 30MB/s. I put it in my Gopro Hero7 and try to record 4K video and error message came up "Card too slow". So obviously this cards had the wrong label on them. It was supposed to be "V30, U3, Class 10, Ai, XC I. But obviously it only delivered upto 30MB/s? Not possible. I am sending it back to Amazon for refund.

These did not work for us. Tried it in a computer and a camera.

Cheap and works fine

I bought these for a Kawa6 dash cam.They format and record as expected. They are a good value product.

128GB2枚セットを購入。CD3枚入れっぱなしにしておくだけなので、1GBもあれば充分なのですが、まぁ64GB以上買っておけば後々再利用できるかなと。購入時の相場が・32GB→500円・64GB→700円・128GB〜→10円/GBくらいというところ、本品は1枚あたり900円ほどとけっこう安かったので、購入。

Just got these for my dashcam. I was considering getting a generic product at first, but after reading a ton of reviews on several, I thought it best to go with an established global brand.I ran CrystalDiskMark 7 on one with the included adapter and the results are what I expected (see pic). These cards are more than sufficient for my dashcam's write speed.Now these are my first Micro SD cards from Patriot, however I've used their RAM and SSD drives in PC builds before so I trust the brand. And for a pair of 128GB cards for $22.99CAD it's a steal! Happy shopping!P.S. I don't recommend running CrystalDiskMark multiple times on any solid state drive as there are potential risks. Once is enough to gauge the drive's capabilities. Just FYI. Cheers!

These are a great price works to my needs what more can I say thank you
