RAID 5 - Different Speed SATA

The 6gbps connectors are separate from the 3gbps on intel chipsets for raid arrangements. Also I wouldnt recommend raid 5 on a intel chipset or any one that is software raid or psudo-hardware raid because your going to loose a ton if speed. If you can but a 4th drive and go raid 10 youll a get a significant speed boost and double your regundancy of raid5.

For a build I'll be doing in the next month, I've pretty much settled on this MSI mobo. Looking at the specs, it has 2 6GB/s and 4 3GB/s sata ports. 

 

I want to throw in 3 WD Red 3TB drives in RAID 5 along with an 840 EVO boot drive. Assuming I want one of the 6GB/s ports dedicated for the SSD (best choice probably?), can you still set up a RAID array with 3 drives over 2 different speed SATA connectors? I was thinking there might be some issues if the 2 different speed connectors were on different chipsets, but I'm no expert. 

 

Alternatively, is there any real drawback to just using the 3GB/s SATA for each of the HDDs in this config? Thanks!

Hard drives (I think) don't even max out the Sata II 3Gbps bus. You should be sweet :)

As above, I wouldn't bother with it. While yes, you can do a RAID configuration across SATA II and SATA III connectors, I wouldn't recommend using an onboard controller. RAID 5 is a fairly complex layout to control and should be done with a separate controller unless you have a decent solution on the motherboard like some server boards do or even high end consumer boards.
