Take a look at this.

I was first drawn to it by the fact that, unlike many others, MSI has added a slick-looking cover to this PCI-e x4 expansion card. A USB PCI-e expansion is pretty common, I see them a lot but...

I see there are two internal SATA connectors on the interior of the card. What is the purpose of this? Does it speed up transfer to the HDD?

I noticed covers on my msi card for the hdmi, and the slot contacts below. Pretty slick and a good way to protect them and discourage handling in the wrong area. Just like ram, you're not supposed to touch the contact area.

Take a look here:

The PCIE X4 slot provides approximately 800MB/s of bandwidth. The purpose of the internal SATA connectors are if you need extra SATA ports (say if you have a lot of SATA HDD's, and need more SATA port connections). It doesn't necessarily speed up transfers. However even 2 HDD's would never fill up that bandwidth (it would be close to around 300MB/s).

Basically only get this if you need USB3/ and or need extra SATA ports. It's actually quite a nice card.

It uses a marvel 9128 controller. You dont really want this to begin with. It has known issues. If you use marvel look for the 9182 controller.

Much obliged :)  I thought they were in relation to the USB ports. It's a nice idea having extra SATA ports inside the case!
