Hello,

I have a T420s and quite keen to expand some storage without upgrading the HDD.

I currently have a 64GB SD card in slot. Just checking what is the maximum SD Card that i can realiably use in my slot?

I have a Ricoh SD Card slot.

Cheers
Nelson

I've used 64GB cards successfully in similar laptops before.

Hey Dr_st.

I go a 64GB running ok. I wonder if 128 will be fine too. Any idea?

Cheers

It has been documented in at least one place there there was difficulty with a 128GB SDXC card, although it was never fully resolved and could have been a defective card. In theory it should support a card up to 2TB in size with the exFAT file system (though currently the largest available is 512GB).
