SATA III vs PCI-Express x4

[discboy321]

So I am in need of some Help. I have a GA-890GPA-UD3H and would like to know which would work better in a general setup. Either a SATA III vs PCI-Express x4 ?

As luck would have it, I finished working on an Intel motherboard base and started working on an AMD motherboard database. According to your motherboards specifications the motherboard's SATA 3.0 6Gb/s ssd controller is integrated into the SB850 Southbridge chipset. No problems there.

The two PCI-e x16 slots get interesting:

1 x PCI Express x16 slot, running at x16 (PCIEX16)

1 x PCI Express x16 slot, running at x8 (PCIEX8)

That sounds real good except when a device is intalled in the 8 channel slot, the 16 channel slot (video card) is reduced to 8 channels. Here's what Gigabyte has to say about it:

"For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot. The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When PCIEX8 is populated with a PCI Express graphics card, the PCIEX16 slot will operate at up to x8 mode."

In plain English it means the video card will take a performance hit. It's not that bad. There were several tests conducted a while back indicating the video card performance will be reduced somewhere between 5% and 8%. The exact percentage depends on configuration. A user will not notice the performance reduction.

You mentioned PCI-e x4 solid state drives. Although they are fast, they also happen to be expensive. What will you be doing that requires a PCI-e x4 based ssd?

After reading from several sources I realized that the ssd came in two different forms so I was just wondering which one would be less prone to failure. I personally use it for video editing /CAD and my step-kids enjoy playing online multi-player games.
