200gb Hard Drive partitions question

[theHeat]

Hey, I've been debating what to do for the past 2 days.

I'm installing a Seagate 200 gig hard drive on this system:

GigaByte GA-7VT600 1394
AMD XP 1800+ (1.53 ghz) with stock HSF
nVidia GeForce4 Ti4200 128 MB
Crucial 2x256 MB pc2100 RAM
Samsung 52X CD-Rom (not burner)
Floppy

Windows 2000 SP3

I will probably buy a NEC dvd burner from NewEgg for it sometime in the near future, but for now, it's just going to be a cd-rom. I want to make images of games so I can run them off of Daemon Tools and Alcohol 120% instead of having to haul around CDs all the time. I also might want to make a partition for backup data of My Documents just incase the main partition fails.

I was thinking:

80 gig System partition
15 gig Document backup partition
40 gig CD Image partition
65 gig Movie / Storage partition

All of these will be NTFS.

Can you offer comments, suggestions, or maybe other ideas for partitioning strategies?

Thanks a lot.
