SD memory Card for navigation purpose only

Hello. I am interested to know when choosing an SD memory card for navigation purpose only, which VFSMark benchmark criteria are more important than others?
 
If, by "navigation," you mean "accessing files already on the card," then the more important VFSmark figures would be file read, file seek, and record access.
 
Sorry for being not clear. With navigation, I meant using GPS navigation on the Palm. I know that VFSMark benchmark all required criteria for typical use of the SD memory card. However, when one would like to a specific SD card for specific need; i.e. in my case GPS car navigation, then I am interested to know which criteria should be better?
 
Hmmm... I've never used a GPS with a Palm before, so I don't know. (Sorry I sounded unclear about what you were asking--many people use the term "navigation" to refer to getting around in the file structure of a drive.)
 
I personally use Delorme's Street Atlas for Handhelds on my T3 with a Sandisk Ultra II 512 gb card. The read/write speed is great and the program runs flawlessly with or without a gps.

I would suggest any card you purchase needs to have as fast a read/write time as possible as I've run the same program off a standard SanDisk 128 card and it was noticably slower loading and changing map views.
 
thanks for your reply. I agree with you that in general the read/write speed are important. Today, I succeeded to contact the GPS software supplier and they told me that typically the GPS software reads from the card and never writes to the card. Good to know. Thanks to all.
