My name is Jonathon Dodge, I am the lead designer for EGO-360. We developed our new range of microSD cards out of necessity, we were buying thousands of cards every month and our microSD providers were aways giving us delays, price increases and excuses. So I designed our new cards with the best component supplier Samsung. Our class range is class 10 cards are driven by SDR50 and our UHS-I by SDR104.
Now unlike some manufacturers that advertise fast speeds that are way off, we have the average speeds on our website. We test 30 cards in 3 groups, 1000 times. The three test environments ( Hot and Humid), ( Cold and Dry) & ( Office 22C within an Electromagnetic field). We write an encrypted code up to full capacity, verify & delete ( not format) 1000x per card.
Our cards work in most devices that I have tested, I have a 256GB SDXC card (exFat) in my Samsung S4 and the fastest it writes is 13.75mbytes, which is slower than some others.
We are users that have become manufacturers to support users like us....
Thats a fair comment, however we primarily developed these microSD card for ourselves and thought we would put them them out there is see what would happen. We never expected to sell any... Buy or Don't that's an individual choice, we bundle them with our other products.
