Do I need a HBA and are all HBAs compatible with HEXOS

[Uncontrolled Competence]

I am new to this and i have known for a while that i need a NAS but i have never really understood the reason for a HBA. I Have 5 drives that i will put in a RAID and my mother board has  6 SATA connections so do i need a HBA? and if so why?

Any Help is much appreciated.

generally HBA is just "an interface" to connect your HDDs to your CPU. assuming you're using a consumer-grade PC (rather than a server), the sata ports connect to your chipset (a chip that is built in to your motherboard), which does the job a HBA would've done.

hypothetically, lets say you use all 6 sata ports and wanna add more drives? only THEN would you need to get a HBA/RAID card, and allocate it in a PCIE slot
