Will SATA 3 controller max out PCI-E v2 x1 socket ?

Motherboard: GA-P35-DQ6
PCI-Express: version 2.x
Onboard controler: Intel (SATA 300)
New SSD: Kingston HyperX 3K (SATA 600)

Just looking at expansion options for my system, wanting to add a SATA 600 SSD, Kingston Hyper X 3K

I have a spare PCI-E x1 SATA 600 controller card (startech pexsat32) Is it worth installing this into my motherboard's x1 socket - the board is only PCI-Express v2, so this means I'll only see 500MB/s on the x1 socket ?

I suppose it would be preferrable than putting the SSD into the existing SATA 300 socket on the motherboard?

  1. Connect the SSD to the SATA II on the MB, because the add-in card don't work well in some case. Your controller card is better work on the HDD but not for SSD, you need a pci-e X4 to get the maximum performance from the SSD.
