There were several PCMCIA cards, but they were very limited and the
reviews noted the limitations.
Sandisk's only supported up to 1GB for example. Another was rated as
"junk" by many users (newegg reviews). Another was rated as being
very slow.
During that Google research and checking sites like newegg, I saw
expresscard listed, and did a Google on "Latitude D520 expresscard"
and saw that the PCMCIA slot also supports expresscard.
Once I found that out then I found a lot more cards that could be used
as a SD card reader, with a lot higher rankings.
