Promise SATA TX4 (PDC20318) is supported by ATA(4) driver. If you need performance, also consider other components besides SATA controller. For example typical desktop pc motherboards only have one PCI bus connecting all slots. 4 SATA disk can easily top the 133MB/s bandwidth of PCI 32bit/33Mhz. Under this situation it will not be better even if you seperate disks onto two cards. Jia-Shiun.
