Hi Experts,

I have a windows XP machine with 4GB RAM, and 4 SATA HDDs installed. I'm shunting some large files (some 1 > GB) and in total ~700GB across a LAN (Restoring a server)

This is ok so far, I'm using robocopy and it seems ok, although the machine slows down quite a bit.

Problem. On other HDD's I get almost no response. It's as though the disk controller is flooded and won't process writes on the other HDDs in the machine which aren't involved in the big transfer.

I want to keep working on my PC but it's almost hung. I've tried installing a PCI sata/ide card and hooking my big transfer drive to this card- thinking that an extra channel might solve the problem but it didn't.

My motherboard is a Gigabyte P965.

I have heard that disk channels are a major factor which differentiates servers from PC's pretending to be servers :)
