|
|
The Serial ATA [SATA] bus is defined over two separate connectors,<br/>
|
|
one connector for the data lines and one for the power lines [shown left].<br/>
|
|
A Serial ATA
|
|
Hard drive may also have a third connector for legacy <a href=

"IDE Connector Pin Out and Parallel ATA Bus Description">PATA</a> power
|
|
connections.<br/>
|
|
The PATA power connector may be used in instead of the SATA
|
|
power cable<br/> to supply a connection which is more rugged and reliable then the
|
|
SATA-1 power connection.<br/>
|
|
The PATA interface is not visible in the diagram.</p>
|
|
<p>The Serial ATA interface cable consists of four conductors in two differential pairs,<br/> plus three ground connections.<br/>
|
|
The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 inches).</p>

interface to handle older Hard Disk Drives [HDD]. Place your main Disk
|
|
Drives on the Serial ATA interface if possible and the older drives on
|
|
the PATA interface ~ as a back-up drive. The SATA interface is much
|
|
faster then the PATA interface, but depending on the disk platter speed,
|
|
a transfer increase may not be seen. Here is a chart of <a href=

|
<p>SATA signal names are with respect to the Host, the device connected to
|
|
the host reverses the signal names. Transmit pins connect to Receive pins
|
|
on the other device. The SATA connector is keyed at pin 1. These pin outs
|
|
for the Serial ATA connector are not compatible with the legacy <a href=

|
|
<p>The Serial ATA interface [SATA] is the serial version of the IDE [ATA]
|
|
spec. SATA uses a 4 conductor cable with two differential pairs [Tx/Rx],
|
|
plus an additional 3 grounds pins and a separate power connector. Data
|
|
runs at 150MBps [1.5GHz] using <a href=
|
|
"http://www.interfacebus.com/Definitions.html#8B_10B" title=
|
|
"Encoding 8-bit data bytes to 10-bit Transmission Characters">8B/10B</a>
|
|
encoding and 250mV signal swings, with a maximum bus length of 1 meter.
|
|
SATA enhancements move the data transfer speed to; 300MBps [3.0Gbps], and
|
|
then 600MBps [6.0Gbps]. The current speed for SATA is 300Mbps [3Gbps].
|
|
Shielded external SATA [eSATA] data cable runs out to a maximum of
|
|
between 3 feet and 6 feet. eSATA cables are used external to the chassis
|
|
or case.</p>

<b><u><font size="+1">Fun (or forgotten) fact </font></u></b>
|
|
<br/>
|
|
What does the acronym SATA stand for? Most sites gloss over it and only provide "Serial ATA", but what is the ATA part? Turns out that has quite a history.
|
|
and only a very few sites will report that the acronym came about when IDE was standardized, the name for the new standard was (as most report) "ATA" or "AT Attachment".
|
|
What the "AT" stands for? Who only lists part of an acronym when giving a definition! I don't blame them,
|
|
This one is buried and all but forgotten, a sure beer bet for your geek buddies as they will almost certainly not know this one.
|
|
<br/>
|
|
Drum roll please..... The complete definition for SATA is: "<font color="#FFFFFF">Serial Advanced Technology Attachment</font>"<---Font is white on white, highlight with mouse to reveal the answer.
