After much searching thru the internet forums for comments, here's the conclusion:-
1. Belkin Firewire Media Reader is VERYYYY SLOOWWW...(<300kbps) 1GB transfer may take 45 minutes to 1 hour to complete. This potentially will drain the iPod totally. :thumbsd:
2. Using the iPod as a Storage device uses more battery life than normal MP3 playing, as the hard disk is in continuous spin. :thumbsd:
3. Belkin Digital Camera Link is slighty faster (abt 0.8Mbps). This will reduce the time compared to the Firewire Media Reader by 2.5 times. However this is still slower than other Photo Storage Devices (ie. Nixvue).This cost abt S$100 when purchased online.
4. If one already have an iPod, then maybe can look at the Belkin Digital Camera Link. But for really serious photographer, and transfer speed is an issue, then go for Nixvue, etc...
5. If you do not have an iPod, and you're mainly looking for a Photo Storage, then go for Nixvue, etc...
Well, since I already got a 15GB iPod, will explore the Belkin Digital Camera Link option.
