What folder (directory) structure do you use under Vista?

The reason I ask is, I'm about to do a new install, and I'm thinking about partitioning the drive so all the Vista folders are in one section and then all my data will have its own drive letter. Right now (under XP) I have the same arrangement (XP stuff in C: and data in D. I have nothing under c:\Documents and Settings\Dan\ except a few shortcuts to D: folders.

Alternatively, I can start putting everything under c:\users\dan\documents\ which might be faster since Vista (apparently) starts with that folder. But it probably won't look as neat.

TIA, Dan

C: V64 boot & critical tools [spindle 0 in ejectable pod]
D: user docs (except admin), noncritical apps [spindle 1]
E: backups of stuff on spindle 0 [spindle 2]
F: library (general repository for software, vids, and pix), also mounted as d:\library [spindle 0]
G: video editing [spindle 1]
H: backups of stuff on spindles other than 0 [spindle 0]
I: my user directory, also mounted as d:\users\(me)\my documents [spindle 3]
X: XP32 boot [spindle 0] - rarely used
Y: swap [spindle 3]
Z: swap [spindle 1]
c:\_MNT\(various): other boot partitions and workspace on other spindles, varies depending on booted OS

you can modify drive letter assignments & mountpoints in administrative tools->computer management->disk management; right-click on a partition and select 'change drive letter and paths'
