Cost-effective Two External SATA Ports Adapter
The Promise SATA300 TX4302 SATA PCI adapter offers the premier solution for connecting externally, the latest high-performance SATA 3Gb/s Serial ATA disk drives. With the SATA300 TX4302, users can connect up to four SATA devices offering users a cost-effective solution for upgrading their existing desktop or server systems and being able to move big chunks of data quickly.
SATA 3Gb/s Support
While storage system performance is affected by components throughout the computer system, SATA drives with 3Gb/s can deliver significantly faster burst data throughput. Like a faster data cache, the faster burst rate when using the latest 3Gb/s drives should provide a snappier feel when opening small files and conducting the day-to-day tasks that many desktop and workstation PCs are required to perform.
The controller supports Serial ATA 3Gb/s drives and conforms to CabCon Volume 2 Specification, Serial ATA II Revision 2.5 specification - including Native Command Queuing and Disk Activity LED headers support. In addition to NCQ, 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.
Advanced HBA Features
The low-profile form factor SATA300 TX4302 PCI adapter incorporates many of Promise Technology's advanced host bus adapter features. The 66MHz PCI bus supports up to 266MB/sec burst data transfer rate. The SATA300 TX4302 also includes large LBA support for drives above 137GB and its onboard BIOS automatically identifies and configures drive type (Serial ATA, Ultra DMA mode). Up to two SATA300 TX4302 PCI adapters can be used in the same system supporting up to a maximum of four SATA 3Gb/s HDDs.
