Well its a PCI lane so you shouldnt have any speeds issues especially with HDDs. These have SATA3 ports which can handle SSDs

Thank you so much! I was looking at this one - http://www.amazon.com/StarTech-com-Express-Controller-HyperDuo-Tiering/dp/B00BUC3N74/ref=sr_1_2?s=pc&ie=UTF8&qid=1426876419&sr=1-2&keywords=4-port+sata - any feedback? What's known to be supported in FreeNAS? Browsed around, but didn't see any listing specifically for support.
If I buy the two port version of this do I have to use both ports? If I plug in both do I have to raid them or can it serve for two separate drives?
They most definitely use hardware raid these days, here's why:
Basically universal compatibility
More reliable than software
Better performance (not taxing CPU constantly)
More SATA ports avaliable with them.
To answer your question, don't risk it.
If you really want the security/performance from RAID, get a controller like: https://www.amazon.com/dp/B00BUC3N74/ref=cm_sw_r_cp_api_KqfUAb5WJFBT1
