Page 1 of Max drive for X-box

I`m thinking of buying a max drive memory stick for the x-box but i can`t find too much information on it.
I want to know if i can go to a web site and download new content for my x-box games (eg new tracks for Gotham or the Hurricane pack for Ninja Gaiden), can you do this with max drive or is it just used to download peoples game saves for cheat purposes ????
Thanks in advance........
