Promise Technology SATA300 TX2plus, Bulk SATA300 TX2PLUS Leaflet

The Promise SATA300 TX2plus 2+1 SATA/PATA PCI adapter offers the premier

solution for combining the latest, high-performance SATA 3.0 Gb/s Serial ATA disk

drives with existing Parallel (Ultra) ATA drives using the same controller.With the

SATA300 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 3Gb/s drives.

While storage system performance is affected by components throughout the storage

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 Serial ATA II,

Extensions to Serial ATA 1.0a 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.

For support of legacy parallel ATA devices, the SATA300 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

SATA300 TX2plus also supports parallel ATAPI devices.
