Is 15TB RAID5 with different controllers possible?

[AlExAkE]

I would like to build new htpc/server for myself, and I'm going to use Zotac H67ITX-C-E or Zotac Z68ITX-B-E motherboard with Lian Li PC-Q08B case. The case itself has space for 6 3.5" hard drives, 1 2.5" hdd, and 1 5.25" cd/dvd/blu-ray ROM. Therefor I would need 8 SATA ports available, 1 for DVD, 1 for 2.5" HDD with OS (Windows Home Sever 2011 or Windows 7 Ultimate), and 6 ports to put 3TB HDD on each, for 15TB RAID5 array. Both of those motherboard have 2 6Gbps SATA III ports, and and 2 or 4 3Gbps SATA II ports.

My question is, they probably use a different controllers for the different ports, but does that matter? Can I put a HDD on a SATA III port on Marvel controller and 1 HDD on SATA II port on Intel and make RAID with it? In addition, since the ports are not enough, I will buy RAID controller like this one: MODEL# IXBAY-PX237

Would that work? Or for RAID I need all the ports to be from 1 controller? Keep in mind, all of the controllers support RAID5. This controller here has only 5 internal, and 1 external port, so I cant use it alone to connect 6HDD on it. Can I use the 5 from here, and 1 from the motherboard, to connect 6 3TB hard drives, to create my 15TB RAID5 array? IF not, please give me some solution. Thanks

you cant cross RAID with different controllers, you have to use the same controller. I cant find any that support SATA 6GB/s HDDs but SATA 3GB/s are easily found but far from cheap.

Of course there are cards that support 6GB/s SATAIII, I've used a variant of this LSI Card.

With this card you have MiniSAS to 4 SATA. You have two ports for a total of 8 Connections. You won't max out the card unless your using Raided High End SSDs. Supports most raid types including RAID5. Place just your 15TB raid on the card, and the rest of the drives on the motherboard.

Not to familar with the newer style of connector. I thought that was more geared for a SAS or SCSI type of drives.
