I have an Intel server board and I want to setup the drives on it in RAID 1 but when activating RAID in the BIOS I get the choice to pick between Intel ESRT2 and Intel RST. I'm pretty sure I can use either of these but I really don't understand the difference between them. All I can really find is what it says in the BIOS itself.
-Intel ESRT2 (Powered By LSI*): Supports RAID 0/1/10 and optional RAID 5 using Intel RAID Key. Uses Intel ESRT2 drivers (based on LSI* megasr).
-Intel RST: Provides pass-through drive support. Also provides host based RAID 0/1/10/5 support. Uses Intel RST iastor drivers.
I'd like to keep things simple and really don't understand the difference since they both seem to support the same RAID modes. If someone knows what the difference is or why I might want to pick one over the other please let me know. I've currently got it set using ESRT2 and everything seems to work but I just picked that one randomly.
