I have two SD card.

Working : Panasonic 16MB
Non working : Corsair 1GB

I don't have any information about voltage required by those cards. The 
Panasonic is labelled "Made in Japan". For the Corsair, I just remember 
that it was sold as a "high performance SD".

GGA, GSA and ZDA all at 1/second seems to do the job. Once converted by 
GPSBabel it gives the following GPX points :
<trkpt lat="48.834831667" lon="2.384541667">
   <ele>86.700000</ele>
   <time>2006-10-21T12:48:31Z</time>
   <fix>3d</fix>
   <sat>6</sat>
   <hdop>1.600000</hdop>
   <vdop>2.200000</vdop>
   <pdop>2.800000</pdop>
</trkpt>


I will probably stop logging GSA for long trip if I just kept my 16MB 
card. GSA only add vdop and pdop to the GPX output...
