Hello,

I kind of didn't pay attention to how many SATA ports my motherboard has and I just realized that it only has 2, and I need 3 (HDD, SSD, and CD Drive). Can someone recommend me the cheapest SATA card (I only need one more SATA port) to buy for my computer? Preferable from canadacomputer.com, please.

Also, how exactly do SATA cards work? I know you put them into the PCI slot but I see that there's a USB port at the back of it, what's it for?

thank you
