Well its too late now! I have a budget issue so I ordered the inexpensive 60 gig one. I only intend to put Trainz on it, and maybe Blender and my paint program to make navigating folders easier.My Trainz folder is currently more than 100 gigs and since you need to rebuild the database sometimes you need more available space for that as well so I suggest 60 gigs might well be on the small side.
Cheerio John
My Trainz folder is only about 10 gigs, and I could easily prune it down to a quarter of that, I only ever do ECML and my own routes. I've never done a datbase rebuild, hopefully I won't have to!
Keep your fingers crossed for me.........
