  1. Since each have their own cable, they all have 300MB/s bandwidth which is not shared.

    If you use crappy PCI or PCIe addon cards to get more Serial ATA connectors, then yes your bandwidth may be shared; but the SATA ports on your motherboard provided by your chipset are full speed.

    So with 6 onboard SATA/300 you can have 6 x 300 = 1800MB/s max.
  2. important information , thanks for help me sub mesa
