Performance on SQL 2000

I have a SQL server with one file group that's about 600GB and two files
residing on a clariion array. Index jobs, etc. appear to run faster if I
create more files. I looked at some of microsoft's tpc server benchmarks and
see that they often break up the database into a number of files with 200GB
as the max file size I've seen.
Does anyone out there know of any articles, web sites or whatever that
specifically address this? Are users out there creating large numbers of
files and I'm in the dark? Articles by reputable sources (K. Delaney among
just a few) are what I'm looking for.

otherwise...

the database reside on different disk drives, seeks can be done in parallel
so the overall performance is improved. There are a few cases where
multiple files allow parallel operations which may help performance but this
generally is not as big a factor as splitting logs, indexes and data into
different disks.
