SATA 3Gb/s Support
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.
Parallel
ATA from the Industry Leader
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.
Advanced
HBA Features
The low-profile form factor SATA300 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 SATA300 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). The controller
supports up to two controllers in the same system.
