[postgis-users] WKB and WKT

the advantages/disadvantages of the different formats for storing geometries
are not quite clear to me.
I have started with Postgis (associated with UMN Mapserver) recently and up
to now I am using the WKT format. What about the advantages of the different
formats? I guess WKB needs less disk space and might be better in
performance? Does the WKB format work with the implemented OpenGis-functions
and UMN Mapserver?

Thanks a lot in advance!

Best regards,
