I would like to know if I am buying the right SD card for my DSLR Canon T3i. In the chart attached from Amazon it states that my CPU has to have 128GB of RAM. I only have 16 GB. Does that mean I will not be able to use the card to transfer content of the SD card onto my PC. Also what should I look for when buying a SD card? There are so many numbers on it . It gets confusing. Class 10 , The read/write speed, UHS class I, III. I just need something with large capacity and fast transfer to my PC . Also does the image quality of pictures or video depends on the camera it self and NOT the SD card. Please help me.
