Video Description

There are two connectors on a SATA drive, one is for power and the other is the data connector. A PATA drive has different connectors as well, but the data drive for PATA is much larger than that of SATA. SATA cable has a 7-pin connector and a 12 inch minimum and 1 meter maximum cable length and why this configuration is necessary, and has 4 connection types, one of which allows for connectivity externally to the computer system.

moving on from our display connectors. We now have device connectors. Device connectors don't connect us to our computer to a display device. They connect our computer are motherboard two devices such as input devices out our hard drives output devices such as pregnant printers.
They allow our computer to connect to
devices when our first device connectors that we're going to look at is a Seder connector. Arcee to connector is a seven pin connector with a 1 to 1 relationship between a device and the motherboard. But that means is if we have one port on our motherboard, we have one device that we can plug into with Arcee the connector.
We have a hard drive here, which is a state, a hard drive
and we see how are sage? A connector simply just plugs into the back of our hard drive Here,
there we go. And then our other end of our state, a connector would simply plug into our motherboard. Now, Arcee to connectors do come in a couple different types again. It's gonna be seven pin for data and our power. Our state a power cable is going to look very similar to our data cable, but it's actually going to be a 15 pin
for power are different. State A types are Seda 12 and three and we also have East data are Seda. One is going to be 1.5 gigabits per second transfer rate. Say to two is going to be 3.0 gigabit per second transfer rate and say 23 is going to be 6.0 gigabit per second transfer rate.
You may have heard me mention earlier I mentioned state a six,
in that instance a little bit of a misnomer. Wanna mention, say to six? I meant, say, 23 but say that was transferring at six gigabits per second. So keep that in mind that our actual state of versions are Saito 12 and three. But they transmit at
one gigabit per 2nd 3 gigabit per second and 6.0 gigabit per second with with our state of three or six point gigabit per second going to be our fastest transfer rate,
we also have our e Seita, which stands for external Seita. And then, of course, our status standing for serial advanced technology attachment. Her East Ada transferring at 3.0, he habit per second and R. E. Seda. We find quite often with certain external hard drives and our computer, we can actually
plugs straight into that
e ST a connection and then plug into our external hard drive. The state A cable looks slightly different than our standards say to cable, so we have to use ah e stato hit header, which allows our additional plug in with our computer or may already be built in, which translates from a standard Saito
connector to actually say the connector for external devices. Keep in mind, we do have USB adapters,
which allow us to if we have a say to drive and we need to just read directly from that state of drive and we don't wanna have to put it into our computer and we don't have an e stato attachment,
then we can simply take that USB to say to converter, plug it in and just read the information off of the drive
as if it were an external hard drive. Our next device connected. We're gonna cover sort of the predecessor to say tha is going to be paid A, also known as E i d. We have a drive here r I D E is going to be a 40 pin connection and drives that use paid a or e i D e.
Use four pin molex power are paid a connections paid a standing for parallel events, technology attachment as opposed to serial advanced technology. Attachment 40 pin connector and the cables, which plug into this connector come in 40 cable version and 80 cable versions.
The 80 cable version is the version that we want to use in any of our systems, which still use paid a R i d E.
Because that's what's its
better, faster. And
the additional cables allow for additional data. Channels allow for ground channels for those data channels. Eso They're much more robust cables and in most systems that you'll see still using the pedo slash i d. You'll see them using the 80 table but
getting remember they
40 Cable and the 80 cable still use a 40 pin connector on the pedo transfers at speeds of 100 slash 133 megabits per second. When we're looking at a paid a cable, it's actually color coded. If we laid a cable out here, we'll have a black end with a connector
and then our ribbon cable.
We'll have our gray end if I can find a way to make this a little bit gray and then we'll have a blue connector.
Now, these color codings do help us out when we're setting up our payday connectors to our hard drives wth e black connector is going to actually be
our primary
Our great connectors won't be our secondary drive, and our blue is going to be our motherboard connector. So we were connecting this cable. We want the blue to be going into our motherboard. We want the black cable to be going into our primary drive, and we want the great cable to be going into our secondary drive. And then we want to go ahead and select.
I use our jumpers on our payday drives to select two
cable select mode. We don't want to set any jumpers on our drives that would conflict with that. I just want to let the cable do the work,
put the cable in there properly and then set the cable select mode.
And again, we want to
note that
this uses a four pin. Molex has its power supply. There's no power version of paid idea uses. The four pen Molex Where's Seita? Does have its own 15 pen power connector, and our Molex cable is going to be moved this cable here.
