SATA what Happened? Look here

[Guest]

All drive makers lined up at the starting line, The starter said take your
mark , get set, and fired his Blank off, then fired it again "false start"(no
operating system or consumer desktop or tower mobo support, pci 2.1,2.2
133mb/s max transfer speed), the disk drive companies all kept running and
are still running, the starter, scratched his head and said what are they
doing, Dont they know a false start when they hear one?Moral of the Story:
You Need a "server board or work station board" to get full benefits of SATA
150/s transfer speeds , running minimum 66MHZ bus lines-266MB/s transfer
between disk drives and memory stacks.

Hundreds of dedicated pc users and testors have made this
information
available to the public, I like consumer protection, its fun to
be involved.
WINXP was made and on the market before SATA was released !
Plus some testors have said WINXP bandwidth does not support
fully
SATA,,, tested in PCI 2.1, 2.1 133MB/s enviornment, current
standard
at time WIN XP was released.

Your argument is still flawed because it presupposes all SATA drives will
ultimately be run from the PCI bus. That is only temporary and transitional
for most users. As new boards and chipsets become available that can handle
and were designed for more robust demands most SATA drives will be moved to
new systems that support them and unless they are in some way mated to the
PCI card, they will be connected to these new interfaces.

Currently, some boards do support this, the Intel 865 and 874 chipsets,
which has the benefit of the 266MB/s speed of the northbridge to southbridge
communication channel
http://www.intel.com/design/chipsets/applnots/252729.htm. The next
generation boards and chipsets will see fuller implementation.

Obviously, even at 150MB/s the speed gains that users see will largely be
based what they previously ran and what speeds they were seeing in those
setups but many will see an improvement. Users who change systems every 3
years or so, should see a nice boost as systems with this support become
more prevalent. Nonetheless, your argument presupposes the technology is or
will standstill and that's not happening. If you are saying that users who
add these drives using PCI cards should not expect to see any real gain, you
are correct but the technology and architecture are about to change and as
the new chipsets become available we should start seeing much wider support
by the end of the year or the early part of next year.

SATA is going to replace IDE and it offers other benefits besides what
admittedly are modest speed gains; wasn't ATA 133 a modest speed gain over
ATA100? It offers a simpler connection interface and it uses a narrower
cable which will enhance air flow through the system as IDE ribbon cables
tend to impede airflow. This is an important factor as heat is a major
issue with high speed processors and memory. There should be additional
improvement as manufacturers learn to deal with and take greater advantage
of the new I/O capabilities. While drives began to appear a year ago, will
before most hardware was up to the task, most people using SATA drives are
the tech heads who tend to be early adopters and they are also the most
likely to move these drives as boards with interfaces that can accommodate
become more readily available. That's the way this sort of thing begins,
usually at the top of the pyramid and working its way down.

If you don't want an SATA drive, don't buy one.
