Windows 7: PC slow down when copying large files from RAID0 to eSATA HDD

PC slow down when copying large files from RAID0 to eSATA HDD

Hi.

I want to backup my files ≥5GB each (BDrip). I'm transfering from a RAID0 made of 2 x 1TB Seagate 7200RPM HDD (intel ICH9R) to my 2TB HITACHI 7200RPM HDD (eSATA/JMicron). Normally, everything goes smoothly, but whenever I use Roadkil's Unstoppable Copier (or windows 7 file manager), the file transfer rate is really good (120 MB/s), but the whole PC get sluggish as hell!! No matter what I'm trying to do. Everything is really slow. My Windows partition is in another RAID0 (4 x 250GB Seagate 7200rpm HDD). I'm not reading anything from there. I have 4 GB of RAM and the system says barely 30% of it is used. My quad core CPU is at 20% maximum. The disk source controller and the target disk controller are dfferent (intel - jmicron). So, I don't see where's the problem.
When I'm reading files, or transfering just one or two files, I don't have any problem. It's only when I' trying to backup ~780GB or more at once when this happens.

Any idea of whats going on?

Thank you, and excuse my english.
