slice and partition layouts

[Nikolas Britton]

I'm trying to find in depth info about the proper way to layout drives, 
slices, partions, filesystems, FHS in unix land, also in relation to 
server role types.

I've read Chapters 2 and 3 from the FreeBSD Handbook and Chapter 16, 
from Absolute BSD but they seem to be lacking the detailed info I'm 
looking for.

Basicly I need to know where the heck I put the 25gigs of data thats on 
are old NT server on are new FreeBSD server, In windows I'd just partion 
a drive in two (Drives C: and D:) C: for for OS and Programs and D: for 
Data but in unix the layout is hierarchical and data is stored all over 
the place (/home, /usr, /var)?
