The SATA300 TX4 4-Port SATA 3G PCI Adapter (One Adapter) from Promise Technology offers a low-cost solution for connecting up to four of the latest, high-performance SATA 3 Gbps disk drives to PC motherboards with a PCI interface. While drive capabilities continue to advance at a fast rate, the vast majority of available motherboards still use the PCI interface to connect peripheral devices.
With the SATA300 TX4, users can benefit from a flexible solution that connects the most advanced drives to their existing system.
SATA 3 Gbps Support
The SATA300 TX4 adapter supports Serial ATA 3 Gbps drives and conforms to Serial ATA II, Extensions to Serial ATA 1.0a specification. This support also includes Native Command Queuing and Disk Activity LED headers support. In addition to Native Command Queuing, the controller also supports Tagged Command Queuing with drives that can take advantage of this capability. Command Queuing increases I/O performance by intelligently reordering data requests so that the data can be more quickly accessed than if the commands weren't ordered.

The low-profile form factor SATA300 TX4 adapter incorporates many of Promise Technology's advanced host bus adapter features. The 66 MHz PCI bus supports up to 266 Mbps burst data transfer rate. The SATA300 TX4 also includes large LBA support for drives above 137 GB and its onboard BIOS automatically identifies and configures drive type. The adapter supports up to two controllers in the same system.
