HB recommends the Sandisk Extreme III SD cards.... I use the 20mbps but will soon be getting the 30mbps...

Mbps is the data transfer rate from the processor writing to the card. ...the faster the transfer rate, the less "lag time" there will be from the time you hit "mark waypoint" to the time the unit writes that data to the card and returns the unit to "live" view...

Faster transfer rates also allow recordings to written more smoothly without jumps, skips, lags, in the recording...

Transfer rate will have little effect on software updates because those files are not as large as GPS data...
