Do the machines have built in controller in the motherboard,
or do they have a pci-e card that's hosting the disks?

 From those pci-e cards there is plenty of benchmarks around, and  
basically
they all struggle to get nearby 1GB/s bandwidth.

 From the motherboards i see 0 benchmarks putting disks on them and  
measuring aggregated bandwidth.

Which chip is on the motherboard doing that and how many disks can it  
host?
