Introduction to PCI Express
For the last 10 years, PCI has been the mainstream interface
for personal PCs, with nearly every computer using the
same PCI bus specification—32-bit, running at 33MHz, and
yielding a maximum data-transfer rate of only 133.3Mbps.
In today's information age, with data size growing
exponentially, there is increased demand for faster transfer
rates. This demand led to Intel's development of the PCI
Express standard, which offers increased speed and stability
for data transfers.
Common PCI Express bus forms include x1, x2, x4, x8,
and x16, with each form being characterized by a unique
slot design. A one-path transmission on a one-lane (x1) PCI
Express bus can reach speeds of up to 250MB—nearly
double the standard PCI transmission speed. A 16-lane (x16)
PCI Express bus can reach speeds of up to 16Gbps.
This SATA II RAID 2-Port PCI Express Card (single-chip,
one-lane, PCI-Express-to-two-internal-Serial-ATA-(SATA)-
II-host-controllers) brings server-class features to your
desktop. It supports all Serial ATA II features, including
3.0Gbps SATA II transfer speeds, Native Command
Queuing (NCQ), port multipliers with FIS-based switching,
programmable output-signal swing strengths for longer
external cables or extended backplanes, hot plugging,
enclosure management, and ATAPI device support.
