[lug] SD card reader and fast cards

[Gary Hodges - NOAA Affiliate]

Hi.  I have a few very small form factor computers that use a SD card 
for the system drive.  I'd like to buy faster cards for these computers, 
but I would first like to determine if the card reader in these machines 
will support the cards I want to buy.  I have one of these currently 
running Ubuntu.  Is there a command I can run or a system spec I can 
look for?
