Product Description:
The Promise SATAII150 TX2plus 2+1 SATA / PATA PCI adapter offers the premier solution for combining new, high performance Serial ATA disk drives with existing Parallel (Ultra) ATA drives using the same controller. With the SATAII150 TX2plus, users can connect up to two SATA drives and 2 PATA drives, offering users a cost-effective solution for upgrading their existing storage system with SATA.
The controller complies with Serial ATA II, Extensions to SATA 1.0 specification and features including Native Command Queuing and Disk Activity LED headers. 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 SATAII150 TX2plus controller also supports Serial ATAPI devices.
For support of legacy parallel ATA devices, the SATAII150 TX2plus supports Ultra/ATA devices up to 133MB/sec data transfer rate. Drawing upon Promise's expertise in ATA, the controller incorporates performance enhancing features such as CRC error checking and separate timing for two devices attached to one ATA channel. The SATAII150 TX2plus also supports parallel ATA ATAPI devices.
The low-profile form factor SATAII150 TX2plus 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 SATAII150 TX2plus also includes large LBA support for drives above 137GB, and its onboard BIOS automatically identifies and configures drive type (Serial ATA, Ultra DMA mode).
