T7810 Raid question

Hello,

T7810 Raid question:

I am running a Samsung pcie-m.2 SSD for my main OS drive. (via pci-e adapter)

 Is it possible to set up a raid array of 2 storage drives separate from my main SSD drive?

Wpuld I maybe  need a pci-e raid controller work for this purpose such as the 

Dell PowerEdge PERC 6/i SAS PCIe RAID Controller - T774H  ??

Or what is the recommended hardware raid card for the T7810?

Thanks for your help!
