Where is the SD card reader?

[Shofar]

Pardon my ignorance but I need some help.

Above the "hot" USB and wireless switch is what looks like a PC card slot. Picture indicates maybe SD card - however it seems way too deep for an SD card and not full size for a PC card. (Does anyone use those anymore?)

To the right of the latch is another slot. Not marked at all. It too is way too deep for an SD card.

It is necessary to buy and adapter from Lenovo to use these slots and what are they really for.

X201s.

Thanks for the help.

The slot above the USB port is an ExpressCard slot. The one to the right of the display latch is the card reader slot. It might look too deep, but it fits my SD card flush with the system.
