I'd suggest using a thumb drive connected to the USB Port. I don't actually know the transfer rate/speed, but I transferred 8 Gb in just a few seconds.

I just purchased 5, 8Gb Thumb Drives from Amazon for US$5.95 each. Prices continue to nosedive.

Almost every modern device (including TVs) have a USB Port, not so with SD Card ports.

Just something to consider.
