Matrix Raid Vs. Regular Raid?

[Kasm]

I understand the concept of matrix raid but I have a few questions.

Does matrix raid 0 cause a smaller increase in seek times than regular raid 0 due to less head movement? Where does matrix raid's seek time stand in comparison to not having a raid vs. normal raid?

Is it possible to implement the same idea of putting a volume on the faster sections of HDD without using matrix raid? Like just using raid 0 on both sections, but partition them so one is the "faster drive"?

Are there certain mohterboards that have the sata ports attached to the pcie bus instead of the pci bus? Because I see burst speeds and transfer speeds higher than the bandwidth of the pci bus of 133 MB/s.

Thank you in advance for your help!

Yes. Depends on how spread apart your files end up on the regular RAID setup......too hard to quantify.

Like just using raid 0 on both sections, but partition them so one is the "faster drive"? Yes. One full RAID0 and partition it. Same speed benefit as the Matrix RAID setup you compare it to.

Are there certain mohterboards that have the sata ports attached to the pcie bus instead of the pci bus? Because I see burst speeds and transfer speeds higher than the bandwidth of the pci bus of 133 MB/s. I haven't seen any SATA ports on a PCI bus, you know of a chipset that does?
