I have been using this Micro SD card since about 2 years now, with my Moto G3. And never have I experienced a slowdown till date. I get about 15Mbps write speed on my phone, and it's plenty considering the fact that the phone is not very powerful.
It comes with a 10 year warranty, is temperature resistant and can survive in seawater for 72 hours. Honestly that's a lot of brunt for a memory card, and if it can stand that much, it can definitely serve your purpose well without breaking down. It's a bit expensive compared to the other brands but I think it is totally worth it due to the speed and quality.
