Just go for Sandisk's cheapest 128GB card, and format it to FAT32 with 64KB clusters. Then copy and paste the drive's contents from one drive to the other.
(Just don't copy the faded-out "System Volume Information" folder, it's useless for the new drive, and probably won't copy anyways. It's just stuff Windows needs, not the 3DS.)
