I am going to Vietnam for a couple of weeks in October. This will be the first long trip I have taken since getting my dslr last year so I am expecting to be taking about 1000 photos if not more. What i want to know is the best way to store the files for the duration of the trip? A couple of weeks ago I started shooting a few things in RAW and am hoping to have a decent handle on this by the time I leave the problem is that my memory card now holds about 120 files instead of 620. Is it best to get a type of external hard drive? I wont have access to a computer over there except in internet cafes and i dont really want to spend very much time in them except to write a couple of emails here and there. Any help would be greatly appreciated, Matt.
