Sata III raid on Dell PERC H310 SAS/SATA?

I recently built a budget-ish PC from mostly second hand parts and was wondering if i would be able to upgrade my storage setup.

The motherboard that I'm using is the ASUS P8B75-V [https://www.asus.com/us/Motherboards/P8B75V/] and i completely overlooked the fact that it only has one SATA III port while the rest are SATA II. I'm using a sata 3 SSD for my OS and and a 1tb sata 3 HDD for my steam library. Becuase my HDD is using a sata 2 connection i feel like im not getting the most a far as performance plus i want to pick up another 1tb wd blue for a raid 0 configuration soon.
Since my motherboard doesn't have an onboard raid controller and a lack of sata 3 ports Im trying to find a somewhat inexpensive PCIE sata expansion card that is capable of Raid 0. I came a across this refurbished dell card but cant find much in the way of information on the cards sata III compatibility, or if it'll even work on my win 10 personal rig. I know it'll do 6Gb/s SAS and is backwards compatible with sata II 3Gb/s.

SO my main question is, will i be able to get true sata 3 6Gb/s speeds from a this raid controller?
heres the dell card i was looking into:

Say your WD Blue does like 150MBps read and about the same for write. Okay, well sata 2 can realistically do over 200MBps. So a WD Blue is definitely not restricted by that interface, 7200Rpm hard drives just aren't that fast. Being as the motherboard is B75 it probably will support some hardware based raid off the chipset, but regardless you can still just do a Raid 0 from within windows. You can use the first page of this:

http://www.pcgamer.com/how-set-software-raid-0-windows-and-linux-2015/

Article to see how to setup raid from within windows, and the second page shows how you can do it from within the motherboard bios.

Keep in mind the usual risks of raid 0. If one drive dies, everything stored on both drives is gone.

No need for a raid controller. The fastest WD blue on sale reaches 175 MB/s while SATA II is capable of over 350 MB/s. Raid0 is easily possible with software, especially if you won't need to boot from it.

Thanks for the help! I guess i was confusing the interface speed with the transfer rate.

Thanks for the advice. Since its just my steam library im not to worried about redundancy or drive failure but thanks for the heads up.

Raid 0 is striping. It's for speed, not redundancy.
