Q: What are GT/s?- "Computers that use the PCIe bus express their speed as GT/s"? and what else is the card slot used for?

If I understand correctly the card slot on the Macbook Pro is for flash memory? Can it be used for anything else?

Read http://support.apple.com/kb/HT3553?viewlocale=en_US&locale=en_US

for information on the card slot.

GT/s is gigatransfer per second. It takes into account the overhead of the PCIe bus.

That's the link that I was reading, it says memory but doesn't specify if there is anything else the card port can be used for. I just don't have any knowledge of the SDXC format/uses.

SDXC is flash memory. So whatever you can do with flash memory, you can do with SDXC.

The primary use of SDXC is photography with it being used in many cameras.
