I tested transferring 2 files totalling 35MB using different methods between my aging G4 400 PowerMac (with USB2 PCI card) on which I use Missing Sync instead of Palm Hotsync and a ByteStor Hi-Speed 1GB SD card and Tungsten T3. Here are the results:

1. 'Palm' Hotsync: about 34 mins
   
2. SD card mounted using Missing Sync app: 2:15 mins
   
3. SD card mounted using Card Export app: 1:18 mins
   
4. SD card mounted using USB1.1 card reader: 2:27 mins
   
5. SD card mounted using USB2 card reader: 0:16 mins
