Any boards with 3 SATA controllers?

I'm planning my next high-end build but I'd really like something with 3 different SATA controllers... what I want to accomplish is this:
1. Primary OS drive, perhaps U.2.
2. Two data drives in RAID 1.
3. Other SATA devices including DVD and eSATA port.

I don't really see any boards that can do this, but maybe I haven't looked hard enough. My current main PC has 2 SATA controllers, but only one of them supports RAID (not a problem) but the other only supports drive devices, not ACHI devices. That's really a PITA because if I use my data drives in RAID, I can't obviously run anything else off of that controller, and the other one won't support my DVD drives. Ugh. Don't want to run intimidate that again.
I'm open to waiting a while if there's some new Intel chipset that might be released later this year that WILL support what I want.
TIA

I guess I COULD install a PCIe RAID card... prefer not, if possible.
But on my current Z87 board, for instance, they are very clear you cannot mix RAID drives, and non-RAID drives on the same group of SATA ports. Current board is Asus Z87 Deluxe Quad.

It took me some time to try and get better information from Asus, and do some additional experimentation. Asus documentation is incomplete at best, and their tech support is friendly enough, but they had to research almost every question I ask d them.
In fact, I can choose which particular ports will participate in the RAID array. That's fine for the WD drives, and the eSATA port, but the SSD didn't like that at all. The SSD is booted up, but the Samsung Magician could no longer talk to it. It demands ACHI, not ISA or RAID. So I had to attach the SSD to the other SATA controller ports which according to Asus, only support SATA drives, but my DVD drives are attached there too, and work just fine. That other controller is slightly slower than the native Z87 controller.

So, bottom line, relative to my original question, it looks like I don't actually need 3 SATA controllers if I utilize the M.2 interface for the OS drive. I can mix and match data RAID dives with any of the other SATA devices.
