I am looking to buy the lightest, smallest (in volume) USB/Firewire drive with as much storage capacity as possible, that can be carried around at the most in a trouser pocket (so desktop drives like Lacie's big drives wont cut it). I ebay'ed and found USB key drives with up to 64 GB capacity (I would need more capacity, more than say 100 GB), but I would like to ask here, what are your personal experiences? If you have one to sell pls PM also (with a pic if possible).
