Can a Solid State Drive run on the same controller as a HDD without degrading performance?
I currently have a 10,000rpm WD Raptor and a 7,200rpm 320GB WD HDD which I keep on separate controllers so that my Raptor isn't hobbled. I'm planning to buy an SSD and run all three (or more) drives, but I only have two controllers on my Asus K8N-E Deluxe motherboard — 2xSATA on the nForce chipset and 4xSATA on a Silicon Image controller.
I actually plan to buy another 7,200rpm HDD and configure it like this:
Since Serial ATA uses a separate cable for each drive, having all three drives on the same controller shouldn't affect hard drive speed. You'd probably notice a slight difference between the drives on the native SATA controller and the ones on the SI controller, since the SI controller is probably sharing the PCI bus.
