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.
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.
Advanced
HBA Features
The low-profile form factor SATA300 TX4 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 TX4 also includes large
LBA support for drives above 137GB, and its onboard BIOS
automatically identifies and configures drive type. The
controller supports up to two controllers in the same
system.
