    IWILL Serial ATA Solution, the fastest storage interface and the standard of next generation!
    The most innovative motherboard manufacturer, IWILL Corporation, shows its superior competence to support the latest storage interface technology, Serial ATA, which is much faster than parallel ATA. It’s designed to address many limitations of the parallel ATA and at the same time maintain100% software/register compatibility with parallel ATA. Serial ATA provides higher data transfer rate (150MB/s) with lower voltage and thinner cable. Following the trend, IWILL offers Serial ATA PCI adapter card , IWILL SATA, and motherboards with Serial ATA on board, IWILL P4G, which will satisfy your need for storage and give you the fastest performance!

    IWILL’s Serial ATA solution
    IWILL is dedicated to provide customers with high-quality, cost effective and innovative solutions for their high-end PC desktop and server need. To follow the trend of storage interface and to meet needs of higher data transfer rate, IWILL proposes comprehensive solution for Serial ATA. Firstly IWILL P4G, motherboard embedded with Serial ATA . IWILL P4G with Serial ATA provides higher data transfer rate that makes your computing system more efficient in storage. Serial ATA cable is thinner and thus improves the airflow and cooling problems, which could happen to parallel ATA cable. Serial ATA interface also simplifies OEM design for compact PC chassis and addresses silicon vendors’ concern about 5 volt tolerance support in future design. IWILL P4G brings next generation storage solution via Serial ATA interface.

    Besides motherboard solution, IWILL also offers add-on card solution: IWILL SATA - a Serial ATA PCI adapter card that uses PCI 32bit/33MHz interface. IWILL SATA supports two Serial ATA connectors, Star Topology (point to point, no hubs) and hot plug. The specification is designed to increase the available bandwidth for each device and therefore each device will obtain the full bandwidth without sharing with each other. Serial ATA is scalable and allow future enhancements to the computing platform. The complete software compatibility with parallel ATA makes Serial ATA the standard of storage interface in next generation and IWILL is going to continue following this trend.

    Why Serial ATA
    Lower voltage
    Parallel ATA is based on TTL signaling, which requires IC to tolerate input signals as high as 5 volts. In the near future, IC manufactured on leading manufacturing processes will not be able to efficiently support to 5 volt signaling voltages. With the upcoming fine lithographies, it will not be feasible to continue supporting 5 volt signaling tolerance. Serial ATA addresses these integration issues by reducing the signaling voltages to approximately 250 millivolts.

    Pin efficiency
    The parallel ATA has 26 signal pins going into the interface chip, while Serial ATA uses only 4 pins, improving the pin efficiency and accommodating a highly integrated chip implementation.

    Improved cable and connector plant
    The current parallel ATA cable and connector plant is a bulky cable nest made up of unwieldy 80 conductor ribbon cables and 40 pin header connectors. Instead of 80 conductor ribbon cables, Serial ATA uses a much smaller serial cable similar with modem cables in appearance. Eliminating the cable nest improves the system’s airflow and cooling and offers more flexibility in chassis design, It also smoothes manufacturability and ease of use by allowing better connector and cable design.

    Master-Slave interaction
    With today’s parallel ATA implementation, pairs of devices share a common cable in a master-slave relationship. This interaction between devices results in the available bandwidth being shared between the devices. Additionally, since the devices on the cable interact, they must be jointly qualified, resulting in the substantial expansion of the system’s integrators’ qualification matrix in order to comprehend all possible combinations of devices. By contrast, Serial ATA is a point-to-point interface where each device is directly connected to the host via a dedicated link. Each device, therefore, has the entire interface bandwidth connected to it, and there is no conflict between devices. This means software can be streamlined, eliminating the overhead associated with coordinating accesses between the master and slave device sharing the same cable.

    Hot-Plug Functionality
    An additional benefit of Serial ATA is it provides the hot-plug functionality, an approach that is not directly supported by parallel ATA. Serial ATA includes all the mechanical and electrical features necessary to allow devices insert directly into receptacles while the system is running (commonly referred to as “hot-plugged“), and the protocol ensures that device discovery and initialization are handled.

    Evolution of Serial ATA specification
    1.Serial ATA 1.0—The first release of the interface will support data transfer rates of up to 150 MB/sec.
    2. Serial ATA 2.0—The specification will be developed in two phases to meet market demands. Phase 1 improves the use of Serial ATA devices in server and network storage applications. Phase 2 adds additional features for the entry-level and mid-range server segments and provides the second generation speed increase (from 150MB/s to 300MB/s) for both server and desktop.

    It is a great mobo.....but their first generation SATA card I suggest you look at the PCB a little closer....Tell me what chip is controlling the serial ATA bus (get specific specs, because I am under the impression that the first release uses a legacy controller from Promise and that the performance is in par with current ATA cards)....I hope I am wrong!!!!
