The role that SD and MicroSD cards play in our ever-increasing mobile lifestyle is becoming more and more important. As our devices become more advanced and file sizes become larger, read and write speeds are increasingly crucial to how we interact and use our devices in our daily lives.

Much like the difference a SSD drive makes in a new PC, the same concept applies to SD cards.
