After doing some research I found you probably hit the nail right on the
head for our RAID config.  Raid 5 is great for smaller files.  Where as
RAID 10 is designed for large file transfers.  
We recently acquired a new adaptec controller The (ASR2130SLP) which
does support RAID 10.

Never would I think that -- just wondering if anyone else had been using
a SAMBA server in a like environment and had some information on how
they had set up a smooth running server.
These things are like cars.  Lets get under the hood and do some
tweaking -- knowwhatImean?  Nothing wrong with adding a little extra pep
by tweaking conf files, hosts lists, remove bottlenecks, etc...etc...

Our backup server for this system is 1/2 the machine and ran fine for 2
weeks while we waited on hardware.  Quite a bit slower and lots of
complaints about access speeds etc...but nary an issue.

Hmmm....are there any packages out there that can be installed to
monitor this? 
Anyone know if Nagios monitors items of that detail -- or have the
ability?  I will havet to look into that.
