2 things jump out:
	1. As has already been pointed out that is not a Centos Plus kernel. 
Did you reboot after installing the new kernel? (You have to reboot for 
a kernel update in order to be running the new kernel).
	2. 1 hour to copy 100GB sounds like a very good speed. Obviously the 
eSATA interface will be the fastest as it will the the same as having it 
plugged directly into the SATA controller. For reference I recently 
copied 73GB from an internal SATA drive to an internal (software) raid0 
array (made up of 2 SATA disks), and that took 1.5hours.
